Other Parts Discussed in Thread: SRC4192, SRC4193

I have designed my DAC using SRC4192. Now, I am using PIC24F to control SRC chip. For extra feature's like volume control and software mute I migrated to SRC4193. what things I need to consider to switch between SRC4192 to SRC4193?

The Micro controller sending good SPI data, clk and cs signal.

Parthiv,

The design should be very similar, only now group delay, OWL, FMT, MODE etc. settings will be programmed instead of hard-wired.

What is the minimum value of SPI clk frequency or it doesn't matter up to 25MIPs. Does it matter to be Clk start from low to high or high to low?

Parthiv,

There shouldn't be a minimum. For CS(bar), it must be high to low for write operations.
