DATA SHEET
- 11 -
data is clocked out of the M13X on rising edges of
these clocks. The clock for the first DS1 channel
corresponds to CR1, while the clock for the last
DS1 channel corresponds to CR28. During normal
operation, the DS1 clock signals are derived from
the DS3 clock signal (DS3CR) and are stretched
due to overhead and stuff bit removal. When the
M13X lead is tied low and the DJB control bit is set
to a 1, the internal DJB circuits will be enabled,
which will reduce the amount that these clocks are
stretched, thereby reducing their jitter. During cer-
tain DS3 alarm conditions (programmable via
1TAIS1 and 1TAIS0, bits 5 and 4 in register 20H)
the M13X provides a DS1 clock signal for clocking
out AIS which is derived from the XCK clock lead.
