SINGLE-CHANNEL T1/E1/J1 LH/SH TRANSCEIVER WITH CLOCK RECOVERY AND JITTER ATTENUATOR
REV. 1.0.1
D3
MCLKRATE
Master Clock Rate Select:
The state of this bit programs the
Master Clock Synthesizer to generate the T1/J1 or E1 clock. The
Master Clock Synthesizer will generate the E1 clock when
MCLKRATE = “0”, and the T1/J1 clock when MCLKRATE = “1”.
R/W
0
D2
RXMUTE
Receive Output Mute:
Writing a "1" to this bit, mutes receive
outputs at RPOS/RDATA and RNEG/LCV pins to a "0" state.
NOTE: RCLK is not muted.
R/W
0
D1
EXLOS
Extended LOS:
Writing a "1" to this bit extends the number of
zeros at the receive input before RLOS is declared to 4096 bits.
Writing a "0" reverts to the normal mode (175+75 bits for T1 and
32 bits for E1).
R/W
0
D0
ICT
In-Circuit-Testing:
Writing a "1" to this bit configures all the out-
put pins of the chip in "High" impedance mode for In-Circuit-Test-
ing. Setting ICT bit to “1” is equivalent to connecting the
Hardware
ICT pin to ground.

D5
TXONCNTL
Transmit On Control.
In Host mode, setting this bit to “1” transfers the control of the
Transmit On/Off function to the TXON Hardware control pin.
NOTE: This provides a faster On/Off capability for redundancy
application.
R/W
0
D4
TERCNTL
Termination Control:
In Host mode, setting this bit to “1” transfers the control of the
RXTSEL to the RXTSEL Hardware control pin.
NOTE: This provides a faster On/Off capability for redundancy
application.
