JA[1:0]: Jitter attenuation position , bandwidth and the depth of FIFO select
00= JA is disabled
01= JA in receiver, broad bandwidth, FIFO=64 bits
10= JA in receiver, narrow bandwidth, FIFO=128 bits
11= JA in transmitter, narrow bandwidth, FIFO=128 bits
MONT: Receive monitor n gain select
0= 0 dB
1= up to 26 dB
LP[1:0]: Loopback mode select
00= no loopback
01= analog loopback
10= digital loopback
11= remote loopback
THZ: Transmitter Driver High Impedance Enable
This signal enables or disables transmitter driver. A low level on this pin enables the driver while a high level on this pin places the
driver in high impedance state.
RCLKE: the active edge of RCLK select when hardware control mode is used
0= select the rising edge as active edge of RCLK
1= select the falling edge as active edge of RCLK
