Master Clock. External, independent clock signal required to generate
internal clocks. For T1 applications, a 1.544 MHz clock is required; for E1,
a 2.048 MHz clock. MCLK must be jitter-free and have an accuracy better
than ± 50 ppm with a typical duty cycle of 50%. Upon Loss of Signal (LOS),
RCLK is derived from MCLK.
Transmit Clock. For T1 applications, a 1.544 MHz clock is required; for
E1, a 2.048 MHz clock. The transceiver samples TPOS and TNEG on the
falling edge of TCLK (or MCLK, if TCLK is not present).
