PGA411-Q1: sampling frequency and clock generation gain

Dongbao Zhou

Part Number: PGA411-Q1

Hello,

I have two questions about PGA411-Q1:

1. what's the sampling frequency of angle and velocity?

2. Could you let me know the clock generation amplifier gain? Customer would like to know this value to adjust the external circuit of crystal.

Thanks.

Dongbao,

1.) The digital datapath output is updated at a 10MHz sampling rate. How quickly you can sample this from your MCU depends on the interface used. SPI is commonly used, but it has the slowest throughput due to the 32 bit SPI frame and the maximum 8MHz SPI clock frequency.
2.) I haven't seen this type of request before. Are you sure this is necessary?
