DESCRIPTION
2ICT
I
In Circuit Testing
When this pin is tied "Low" all output pins are forced to high-impedance state
for in-circuit testing.
NOTE: Internally pulled up.
16
ExCLK
I
External Clock Input:
DS1 (1.544 MHz ± 130 ppm) or CEPT E1 (2.048 MHz ± 80 ppm) clock signal is
provided. ExCLK must be an independent clock to guarantee device perfor-
mance for all specifications. This clock must be continuously active (ungapped
or unswitched) and void of jitter for the device to operate properly.
11
TAOS
I
Transmit All Ones:
With this pin tied "High", an AMI encoded all "1’s" signal sent to the transmit
output using ExCLK as the timing reference. A remote loop back has higher
priority over TAOS request.
NOTE: Internally pulled down.
9LOOPB
I
Loopback control.
LOOPB along with LOOPA is used for selecting different loopbacks.
NOTE: Internally Pulled down.
10
LOOPA
I
Loopback control.
LOOPB along with LOOPA is used for selecting different loopbacks.
NOTE: Internally Pulled down.
13
FOFS
O
FIFO Overflow Signal:
This pin is set "High" if the phase jitter of the incoming signal exceeds the toler-
ance of the jitter attenuator’s buffer. This may result in loss of data and Jitter
Attenuator is no longer attenuating jitter.
