\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 provides 4 channels of DDS at 1GS/s.
|
||||
Output frequency 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 provides 70 dB isolation.
|
||||
4410 DDS Urukul comes with AD9910 chips, while 4412 DDS Urukul comes with AD9912 chips instead.
|
||||
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.

\section{Urukul 1-EEM/2-EEM Modes}
|
||||
4410/4412 DDS Urukul can operate with either 1 or 2 EEM connections.
|
||||
It is in 1-EEM mode when only EEM0 is connected, 2-EEM mode when both EEM0 \& EEM1 are connected.
|
||||
2-EEM mode provides these additional features in comparison to 1-EEM mode.
|
||||
\begin{itemize}
|
||||
\item 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 is achieved using the ARTIQ RTIO system.
|
||||
\section{Urukul Single-/Double-EEM Modes}
|
||||
|
||||
\item SU-Servo (4410 DDS Urukul feature) \\
|
||||
SU-Servo requires both EEM0 \& EEM1 to control multiple DDS channels simultaneously using the QSPI interface.
|
||||
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. \\

The SPI signal is driven by the evaluation kit, converted into LVDS signal by propagating through the DIO-tester card, finally arriving at the Mirny card.

Mirny is then connected to the RSA5100A spectrum analyzer for measurement.

Phase noise performance of Mirny was tested using the ADF4351 evaluation kit\repeatfootnote{mirny_thesis}.

Noise response spike can be improved by inserting an additional common-mode choke between the power supply and Mirny.

Note that the common-mode choke is not present on the Mirny card.

\section{Example ARTIQ code}
|
||||
The sections below demonstrate simple usage scenarios of the 4456 Synthesizer Mirny card with the ARTIQ control system.
|
||||
They do not exhaustively demonstrate all the features of the ARTIQ system.
|
||||
The full documentation for the ARTIQ software and gateware is available at \url{https://m-labs.hk}.

\subsection{1 GHz Sinusoidal Wave}
|
||||
Generate a 1 GHz sinusoid from RF0 with full scale amplitude, attenuated by 12 dB.
|
||||
Both the CPLD and the PLL channels should be initialized.
