DS90C363: Data Enable Unexpected Behavior

Brandon Pilmaier

Part Number: DS90C363

Hello,

We use the DS90C363 in our legacy products and are seeing that Data enable is being asserted during horizontal blanking periods for about one clock cycle. Is this expected? We are doing more testing, but we do not believe these are being driven through the DRDY pin.

THank you!

Hi Brandon,

Could you please share how you are finding that DE (data enable) is asserted for additional clock cycles? You could also probe on the input to the DS90C363 on the DE pin to check this.

Best regards,
Ikram
