\section{General Description}
|
||||
|
||||
The 1008 VHDCI Carrier is a 4hp EEM module, part of the ARTIQ/Sinara family. It is a passive adapter card which converts VHDCI connections to or from EEM connections.
|
||||
|
||||
The 1008 VHDCI Carrier is bidirectional; it can be driven by a core device carrier board, or can drive other cards.
|
||||
|
||||
A pair of VHDCI Carrier cards can be paired with VHDCI SCSI-3 cables to carry EEM signals over short distances between crates. Depending on the application, this can serve as a simple, low-cost, low-latency alternative to multiple core devices and ARTIQ DRTIO.

\section{Power}
|

Power supply is required when driving EEM cards. 12V should be supplied through barrel jacks (2.50 mm ID, 5.50 mm OD) either in front panel or at back of card.

\section{General Description}
|
||||
The 4410/4412 DDS Urukul card is a 4hp EEM module, part of the ARTIQ/Sinara family. It adds frequency generation capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC.
|
||||
The 4410/4412 DDS Urukul card is a 4hp EEM module, part of the ARTIQ/Sinara family. It adds frequency generation capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC. It can also be combined with 5018 ADC Sampler to form the ARTIQ SU-Servo configuration.
|
||||
|
||||
It provides 4 channels of DDS (direct digital synthesis) at 1GS/s. Output frequencies from \textless 1 to \textgreater 400 MHz are supported. The nominal maximum output power of each channel is 10dBm. Each channel can be attenuated from 0 to -31.5 dB by a digital attenuator. RF switches (1ns temporal resolution) on each channel provide 70 dB isolation.
|
||||
|
||||
4410 DDS Urukul features AD9910 chips, while 4412 DDS Urukul features AD9912 chips. AD9912 is capable of higher frequency precision (~8 \textmu Hz) than the AD9910 (~0.25 Hz). The ARTIQ SU-Servo configuration is only available for AD9910.
|
||||
4410 DDS Urukul features AD9910 chips, while 4412 DDS Urukul features AD9912 chips. These offer slightly different features and specifications. See below for a comparison between the two.

\section{Model comparison}
|
||||
|
||||
4410 DDS Urukul uses AD9910\repeatfootnote{ad9910} chips, whereas 4412 DDS Urukul uses AD9912\repeatfootnote{ad9912} chips. In general, 4412/AD9912 is capable of much higher frequency resolution, at the cost of more detailed control features provided by 4410/AD9910, such as phase synchronization, digital ramp modulation or DRG, and digital amplitude control. See individual DDS IC datasheets for feature details, especially of AD9910, or ARTIQ code section below for examples of more complex experiments only possible with AD9910. The SUServo configuration is only available for AD9910.

4410/4412 Urukul features a number of indicator LEDs in the front panel. Each of four channel SMA connectors is accompanied by a green LED, used to indicate that RF output is enabled, and a red LED, which activates to indicate a DDS synchronization/PLL issue. Note that when bypassing PLL in ARTIQ (see below) LED may stay on.

\section{Urukul Single-/Double-EEM Modes}
|
||||
|
||||
4410/4412 DDS Urukul cards can operate with either a single or double EEM connections. When only EEM0 is connected, the card will act in single-EEM mode; when both EEM0 and EEM1 are connected, the card will act in double-EEM mode. 2-EEM mode when both EEM0 \& EEM1 are connected. Double-EEM mode provides these additional features in comparison to single-EEM mode:
|
||||
\begin{itemize}
|
||||
\item \textbf{1 ns temporal resolution RF switches} \\
|
||||
Without EEM1, the only way to access the switches is through the CPLD, using SPI. \\
|
||||
With EEM1, RF switches can be controlled as a TTL output through the LVDS transceiver. 1 ns temporal resolution can then be achieved using the ARTIQ RTIO system.
|
||||
4410/4412 DDS Urukul cards can operate with either a single or double EEM connections. When only EEM0 is connected, the card will act in single-EEM mode; when both EEM0 and EEM1 are connected, the card will act in double-EEM mode.
|
||||
|
||||
\item \textbf{SU-Servo (4410 DDS Urukul feature)} \\
|
||||
SU-Servo requires both EEM0 \& EEM1 to allow the control of multiple DDS channels simultaneously using the QSPI interface.
|
||||
Double-EEM mode additionally provides 1 ns temporal resolution RF switches and phase synchronization feature. Without EEM1, the only way to access the switches is through the CPLD, using SPI. With EEM1, RF switches can be controlled as a TTL output through the LVDS transceiver. 1 ns temporal resolution can then be achieved using the ARTIQ RTIO system. Double-EEM mode is also recommended for the SUServo configuration.

\subsection{Voltage-controlled DDS amplitude (SU-Servo only)}
|
||||
The SU-Servo feature can be enabled by integrating the 4410 DDS Urukul with a 5108 Sampler. Amplitude of the DDS output can be controlled by the ADC input of the Sampler through PI control, characterised by the following transfer function:
|
||||
|
||||
\[H(s)=k_p+\frac{k_i}{s+\frac{k_i}{g}}\]
|
||||
|
||||
In the following example, the amplitude of DDS is proportional to the ADC input from Sampler. First, initialize the RTIO, SU-Servo and its channel. Note that the programmable gain of the Sampler is $10^0=1$ and the input range is [-10V, 10V].
|
||||
|
||||
\inputcolorboxminted{firstline=10,lastline=17}{examples/suservo.py}
|
||||
|
||||
Next, setup the PI control as an IIR filter. It has -1 proportional gain $k_p$ and no integrator gain $k_i$.
|
||||
|
||||
\inputcolorboxminted{firstline=18,lastline=25}{examples/suservo.py}
|
||||
|
||||
Then, configure the DDS frequency to 10 MHz with 3V input offset.
|
||||
When input voltage $\geq$ offset voltage, the DDS output amplitude is 0.
|
||||
|
||||
\inputcolorboxminted{firstline=26,lastline=30}{examples/suservo.py}
|
||||
|
||||
SU-Servo encodes the ADC voltage in a linear scale [-1, 1]. Therefore, 3V is converted to 0.3. Note that the ASF of all DDS channels are capped at 1.0 and the amplitude clips when ADC input $\leq -7V$ with the above IIR filter.
|
||||
|

Enter the actual EEM port numbers used on the core device. Any ports can be used. If using only one Urukul (and half of the available Sampler channels), the \texttt{urukul1\_ports} field may be left out entirely.
|
||||
|
||||
For the \texttt{clk\_sel} field, \texttt{0} represents the internal 100 MHz oscillator, \texttt{1} represents SMA input, and \texttt{2} represents MMCX input.

% miraculously, this newpage is good for both Sampler and Urukul datasheets!

% will probably break if any sections are added though

\section{Example SU-Servo Code}
|
||||
|
||||
In SU-Servo configuration, amplitude of the Urukul DDS output can be controlled with the Sampler ADC input through PI control, characterised by the following transfer function:
|
||||
|
||||
\[H(s)=k_p+\frac{k_i}{s+\frac{k_i}{g}}\]
|
||||
|
||||
In the following example, the DDS amplitude is set proportionally to the ADC input from Sampler. We initialize SU-Servo and all channels first. Note that the programmable gain of the Sampler is $10^0=1$ and the input range is [-10V, 10V].
|
||||
|
||||
\inputcolorboxminted{firstline=10,lastline=17}{examples/suservo.py}
|
||||
|
||||
Next, we set up the PI control as an IIR filter. It has -1 proportional gain $k_p$ and no integrator gain $k_i$.
|
||||
|
||||
\inputcolorboxminted{firstline=18,lastline=25}{examples/suservo.py}
|
||||
|
||||
Then, configure the DDS frequency to 10 MHz with 3V input offset. When input voltage $\geq$ offset voltage, the DDS output amplitude is 0.
|
||||
|
||||
\inputcolorboxminted{firstline=26,lastline=30}{examples/suservo.py}
|
||||
|
||||
SU-Servo encodes the ADC voltage on a linear scale [-1, 1]. Therefore, 3V is converted to 0.3. Note that the ASF of all DDS channels ss capped at 1.0 and the amplitude clips when ADC input $\leq -7V$ with the above IIR filter.
|
||||
|
||||
Finally, enable the SU-Servo channel with the IIR filter programmed beforehand:
|
||||
|
||||
\inputcolorboxminted{firstline=32,lastline=33}{examples/suservo.py}
|
||||
|
||||
A 10 MHz DDS signal is generated from the example above, with amplitude controllable by ADC. The RMS voltage of the DDS channel against the ADC voltage is plotted. The DDS channel is terminated with 50\textOmega.

DDS signal should be attenuated. High output power affects the linearity due to the 1 dB compression point of the amplifier at 13 dBm output power. 15 dB attenuation at the digital attenuator was applied in this example.
