Figure B2. Serial Ports-to-Transmitter Timing (slave mode)
When the part is finished transmitting the pream-
ble of a sub-frame, the internal signal LDS rises
to parallel-load R2 into R3 for transmission. Af-
ter RST, the part synchronizes the audio port to
IMCK as shown in Figure B2. Since PLD is
based on FSYNC and LDS is based on IMCK, if
FSYNC moves with respect to IMCK until PLD
and LDS occur at the same time, the data would
not be properly loaded into R3. If LDS and PLD
overlap, an internal reset is initiated causing the
timing to return to the initial state shown in Fig-
ure B2.

* Although the ’-CP’ and ’-CS’ suffixed parts are guaranteed to operate over 0 to 70 °C, they are
tested at 25 °C only. If testing over temperature is desired, the ’-IP’ and ’-IS’ suffixed parts are
tested over their specified temperature range.
