Clock
MCLK
Input
AK19
MCLK: Master Clock Input
MCLK provides a stable reference timing for the IDT82P2821. MCLK should be a clock with +/
-32 ppm (in T1/J1 mode) or +/-50 ppm (in E1 mode) accuracy. The clock frequency of MCLK
is informed to the device by MCKSEL[3:0].
If MCLK misses (duty cycle is less than 30% for 10 s) and then recovers, the device will be
reset automatically.

MCKSEL[3:0]: Master Clock Selection
These four pins inform the device of the clock frequency input on MCLK:
CLKT1
Output
AH18
CLKT1: 8 KHz / T1 Clock Output
The output on CLKT1 can be enabled or disabled, as determined by the CLKT1_EN bit (b1,
When the output is enabled, CLKT1 outputs an 8 KHz or 1.544 MHz clock, as selected by the
CLKT1 bit (b0, CLKG). The output is locked to MCLK.
When the output is disabled, CLKT1 is in High-Z state.
CLKE1
Output
AG18
CLKE1: 8 KHz / E1 Clock Output
The output on CLKE1 can be enabled or disabled, as determined by the CLKE1_EN bit (b3,
When the output is enabled, CLKE1 outputs an 8 KHz or 2.048 MHz clock, as selected by the
CLKE1 bit (b2, CLKG). The output is locked to MCLK.
When the output is disabled, CLKE1 is in High-Z state.
