82P2816BBG
IDT82P2816
16(+1) CHANNEL HIGH-DENSITY T1/E1/J1 LINE INTERFACE UNIT
Functional Description

3.6.3
MCLK, MASTER CLOCK INPUT
MCLK provides a stable reference timing for the IDT82P2816. 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 set by pins
MCKSEL[3:0] and can be N x 1.544 MHz or N x 2.048 MHz with 1
≤ N ≤
8 (N is an integer number). Refer to MCKSEL[3:0] pin description for
details.
If there is a loss of MCLK (duty cycle is less than 30% for 10 s), the
device will enter power down. In this case, both the receive and transmit
circuits are turned off. The pins on the line interface will be in High-Z
state. The pins on receive system interface will be in High-Z state or in
low level, as selected by the RHZ bit (b6, RCF0,...). The input on the
transmit system interface is ignored and the output on the transmit
system interface will be in High-Z state. Refer to Section 3.2.7 Receiver
If MCLK recovers after loss of MCLK the device will be reset auto-
matically.
3.6.4
XCLK, INTERNAL REFERENCE CLOCK INPUT
XCLK is derived from MCLK. For the respective channel, it is 1.544
MHz in T1/J1 mode or 2.048 MHz in E1 mode. XCLK is used as select-
able reference clock for
pattern /AIS generation
