From ce563bdcf1054f0b3aa0dc155cc3fa590ba6107b Mon Sep 17 00:00:00 2001 From: occheung Date: Wed, 19 Jan 2022 12:29:38 +0800 Subject: [PATCH] 4410-4412: remove fractions & literal word symbols Some of them are added in 05eba6fa. Very certain the fraction symbols are rarely used in any other datasheets to express decibels, if any at all. --- 4410-4412.tex | 22 +++++++++++----------- 1 file changed, 11 insertions(+), 11 deletions(-) diff --git a/4410-4412.tex b/4410-4412.tex index 34f1bed..f9ac6fd 100644 --- a/4410-4412.tex +++ b/4410-4412.tex @@ -351,18 +351,18 @@ and corresponding test results\footnote{\label{sinara354}https://github.com/sina \hline Frequency\repeatfootnote{urukul_wiki} & $f_{out}$ & 1 & & 400 & MHz & \\ \hline - Digital attenuation\repeatfootnote{attenuator} & $\frac{P_{out}}{P_{dds}}$ & -31.5 & & 0 & dB & \\ + Digital attenuation\repeatfootnote{attenuator} & & -31.5 & & 0 & dB & \\ \hline Resolution & & & & & & \\ - \hspace{3mm} Frequency\repeatfootnote{ad9910}\textsuperscript{,}\repeatfootnote{urukul_wiki} & $Q_f$ & & 0.25 & & Hz & AD9910 \\ + \hspace{3mm} Frequency\repeatfootnote{ad9910}\textsuperscript{,}\repeatfootnote{urukul_wiki} & & & 0.25 & & Hz & AD9910 \\ & & & 8 & & $\mu$Hz & AD9912 \\ - \hspace{3mm} Phase offset\repeatfootnote{ad9910}\textsuperscript{,}\repeatfootnote{ad9912} & $Q_\theta$ & & 16 & & bits & AD9910 \\ + \hspace{3mm} Phase offset\repeatfootnote{ad9910}\textsuperscript{,}\repeatfootnote{ad9912} & & & 16 & & bits & AD9910 \\ & & & 14 & & bits & AD9912 \\ - \hspace{3mm} Digital amplitude\repeatfootnote{ad9910} & $M_{asf}$ & & 14 & & bits & AD9910 \\ - \hspace{3mm} DAC full scale current\repeatfootnote{ad9910}\textsuperscript{,}\repeatfootnote{ad9912} & $M_{I}$ & & 8 & & bits & AD9910 \\ + \hspace{3mm} Digital amplitude\repeatfootnote{ad9910} & & & 14 & & bits & AD9910 \\ + \hspace{3mm} DAC full scale current\repeatfootnote{ad9910}\textsuperscript{,}\repeatfootnote{ad9912} & & & 8 & & bits & AD9910 \\ & & & 10 & & bits & AD9912 \\ \hspace{3mm} Temporal (I/O Update)\repeatfootnote{urukul_wiki} & $\Delta t$ & & 4 & & ns & \\ - \hspace{3mm} Digital attenuation\repeatfootnote{attenuator} & $Q_{att}$ & & 0.5 & & dB & \\ + \hspace{3mm} Digital attenuation\repeatfootnote{attenuator} & & & 0.5 & & dB & \\ \thickhline \end{tabularx} \end{threeparttable} @@ -390,13 +390,13 @@ The tabulated performance characteristics are produced using the following setup \hline RF switch\repeatfootnote{sinara354} & & & & & &\\ \hspace{3mm} Rise to 90\% & $t_{on}$ & & 100 & & ns & \\ - \hspace{3mm} Isolation & $\frac{P_{off}}{P_{dds}}$ & & 70 & & dB & \\ + \hspace{3mm} Isolation & & & 70 & & dB & \\ \hspace{3mm} Turn-on chirp & $\gamma$ & & & 0.1 & deg/s & Excluding the first $\mu$s\\ \hline - Crosstalk\repeatfootnote{sinara354} & $\frac{P_X}{P_{out}}$ & & -84 & & dB & Victim RF switch opened \\ + Crosstalk\repeatfootnote{sinara354} & & & -84 & & dB & Victim RF switch opened \\ & & & -110 & & dB & Victim RF switch closed \\ \hline - Cross-channel-intermodulation\repeatfootnote{sinara354} & $IM$ & & -90 & & dB & \\ + Cross-channel-intermodulation\repeatfootnote{sinara354} & & & -90 & & dB & \\ \hline Phase noise\repeatfootnote{sinara354} & $\mathcal{L}(f)$ & & -85 & & dBc/Hz & 0.1 Hz \\ & & & -95 & & dBc/Hz & 1 Hz \\ @@ -408,10 +408,10 @@ The tabulated performance characteristics are produced using the following setup & & & -128 & & dBc/Hz & 1 MHz \\ & & & -149 & & dBc/Hz & 10 MHz \\ \hline - Second-order harmonics\repeatfootnote{sinara354} & $\frac{P_{n=2}}{P_{n=1}}$ & & -40 & & dB & 6 dBm output \\ + Second-order harmonics\repeatfootnote{sinara354} & & & -40 & & dB & 6 dBm output \\ & & & -34 & & dB & 10.5 dBm output \\ \hline - Third-order harmonics\repeatfootnote{sinara354} & $\frac{P_{n=3}}{P_{n=1}}$ & & -54 & & dB & 6 dBm output \\ + Third-order harmonics\repeatfootnote{sinara354} & & & -54 & & dB & 6 dBm output \\ & & & -28 & & dB & 10.5 dBm output \\ \hline Power consumption (AD9910)\repeatfootnote{urukul_wiki} & $P$ & & 7 & & W & 4x 400 MHz, 10.5 dBm, 52\degree C\\
