PCM1802: Question about Audio Data Interface Timing

Takeshi Sasaki

Part Number: PCM1802

Hi team,

Could you give me comment on following customer questions?

Q1. At page18, rise/fall time of all signals describes 10ns. What does it mean "all signals"? Does it mean FSYNC, LRCK, BCK, DOUT only or should it include any other signals at the device, such as PDWN?

Q2. To confirm, can the device accept rise/fall time of PDWN signal as 25ns?

Best regards,

Hi Takeshi,

The 10ns spec is referring to the clock and data signals in the timing diagram, this does not apply to PDWN. a rise/fall time of 25ns for PDWN is perfectly acceptable.

Best,

Zak
