The relationships between Audio interface signals (DA-XCK, DA-LRCK, DA-BCK) and each sampling
frequency are as follows:
Sampling frequency: 44.1 kHz (For CD-DA and Video-CD)
DA-XCK
384*fs=16.934MHz
DA-BCK
DA-XCK/8=2.1168MHz
DA-LRCK
DA-BCK/48=44.1kHz=fs
Sampling frequency: 48kHz (for DVD)
DA-XCK
384*fs=18.432MHz
DA-BCK
DA-XCK/8=2.304MHz
DA-LRCK
DA-BCK/48=48kHz=fs
Sampling frequency: 96kHz (for DVD)
DA-XCK
384*fs=36.864MHz
DA-BCK
DA-XCK/8=4.608MHz
DA-LRCK
DA-BCK/48=96kHz=fs
20MHz X'TAL (X1601)
20MHz clock is generated by attaching 20MHz crystal trembler to SH
µ
-COM (IC1601) and used as the
system clock of SH
µ
-COM. This system clock is supplied to I/F GATE ARRAY (input at IC1101 39 pin) and
used as clock.
