External Clock Input

Description

CN004 and CN005 are PCM audio interface clock outputs (System Clock, LRCK, BCK, and DATA).
CN004 is a buffered output with a mounted logic buffer IC. CN005 is a direct output from DIR9001.

Caution: Pins on the right side are GND.

•

SCKO : System Clock (128/256/384/512fs)

•

BCKO : PCM audio, BCK clock (64fs)

•

LRCKO : PCM audio, LRCK clock (fs)

•

DOUT : PCM audio, DATA clock

The external clock can be connected at CN002 (not mounted) by removing the mounted XTAL. This alows
the user to confirm operation of the DIR9001 by another clock source.
