CLOCK INPUTS AND OUTPUTS
The IDT82P2816 provides two kinds of clock outputs:
Free running clock outputs on CLKT1 and CLKE1
Receiver clock outputs on REFA and REFB
- selected from any of the 17 recovered line clocks
- driven by MCLK (free running)
- driven by external CLKA/CLKB input
A Frequency Synthesizer is also available to scale REFA to 8
different frequencies.
The following Clock Inputs are provided:
MCLK as programmable reference timing for the IDT82P2816.
CLKA and CLKB as optional input clock source for REFA and
REFB respectively
3.6.1
FREE RUNNING CLOCK OUTPUTS ON CLKT1/CLKE1
An internal clock generator uses MCLK as reference to generate all
the clocks required by internal circuits and CLKT1/CLKE1 outputs.
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 1.544/2.048 X N
MHz (1
≤ N ≤ 8, N is an integer number), as determined by
MCKSEL[3:0]. Refer to Chapter 2 Pin Description for details.
The outputs on CLKT1 and CLKE1 are free running (locking to
MCLK). The output of CLKT1 is determined by the CLKT1_EN bit (b1,
CLKG) and the CLKT1 bit (b0, CLKG). Refer to Table-23. The output of
CLKE1 is determined by the CLKE1_EN bit (b3, CLKG) and the CLKE1
bit (b2, CLKG). Refer to Table-24.
