Part Number: SRC4192
What are the differences between the SRC4192 and the SRC4193?
Regards,Collin WellsPrecision ADC Applications
Here is a table breakdown of the differences between the SRC4192 and the SRC4193.
Programmable Digital Output Attenuation
Supported; Digital attenuation control is adjustable from 0 dB to –127.5 dB in 0.5-dB steps.
Direct Downsampling option for Decimation filter
Supported; This can be used in cases when aliasing is not an issue (ex: when output fs is equal or greater than input fs).
Advantage: Significant reduction is group delay associated w Decimation filter, allowing lower latency SRC.
Supported; This can be used as an indicator or flag output for host device.
Reset and Power-down Operation
Using RST pin; With external clock source active, assert RST low for min 500ns
Using RST pin; BUT we need to wait at least 500uS after RST rising edge due to internal logic requirements;
SRC4193 also supports power-down mode [Using PDN bit of Control Register 1]
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
