Clock Synthesizers
Clocks to operate LIUs, jitter attenuators, framers, BERTs and HDLC controllers can be synthesized from a
single clock input for both E1 and T1 operation (10MHz, 19.44MHz, 38.88MHz or 77.76MHz on the
CLK_HIGHpin or 1.544MHz or 2.048MHz on the
MCLK pin)
Clocks to operate the TDMoP clock recovery machines can synthesized from a single clock input (10MHz,
19.44MHz, 38.88MHz or 77.76MHz on the
CLK_HIGH pin)
Clock to operate TDMoP logic and SDRAM interface (50MHz or 75MHz) can be synthesized from a single
