>Just curious - what is a cs4321 ?
[NB: This is my own understanding of events, and is in no way
In the beginning Analog Devices created the AD1848; the customers
looked upon it, and decided it was good. They bought it in great
quantities (and still do).
Crystal Semiconductor didn't want to miss out on a good thing, so they
cloned the AD1848, and called their clone the CS4248. They then
decided that they could make it better. They added 16-sample input
and output FIFOs, and 16 more registers. The result was the CS4231.
Later they added a serial port and some more refinements, and that
was the CS4231A.
Analog Devices didn't want to miss out on the fun, so we created the
AD1845. It improves on the CS4231 by adding the ability to set any
sample rate between 4 kHz and 50 kHz with 1 Hz resolution.
This family tree will help to explain:
