3.3
INPUT CLOCKS & FRAME SYNC SIGNAL
Altogether 5 clocks and 1 frame sync signal are input to the device.
3.3.1
INPUT CLOCKS
The device provides 5 input clock ports.
According to the input port technology, the input ports support the fol-
lowing technologies:
PECL/LVDS
CMOS
According to the input clock source, the following clock sources are
supported:
T1: Recovered clock from STM-N or OC-n
T2: PDH network synchronization timing
T3: External synchronization reference timing
IN1, IN2 and IN5 support CMOS input signal only and the clock
sources can be from T1, T2 or T3.
IN3 and IN4 support PECL/LVDS input signal only and automatically
detect whether the signal is PECL or LVDS. The clock sources can be
from T1, T2 or T3.
For SDH and SONET networks, the default frequency is different.
SONET / SDH frequency selection is controlled by the IN_SONET_SDH
bit. During reset, the default value of the IN_SONET_SDH bit is deter-
mined by the SONET/SDH pin: high for SONET and low for SDH. After
reset, the input signal on the SONET/SDH pin takes no effect.
3.3.2
FRAME SYNC INPUT SIGNALS
A 2 kHz, 4 kHz or 8 kHz frame sync signal is input on the EX_SYNC1
pin. It is a CMOS input. The input frequency should match the setting in
the SYNC_FREQ[1:0] bits.
The frame sync input signal is used for frame sync output signal syn-
details.
