PATTn[1:0]: Transmit test pattern select (per channel control)
In hardware control mode, these pins select the transmit pattern for channel n (n=1 or 2)
00 = normal
01= All Ones
10= PRBS
11= transmitter power down
JA[1:0]: Jitter attenuation position, bandwidth and the depth of FIFO select (global control)
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
MONTn: Receive Monitor n gain select (per channel control)
In hardware control mode with ternary interface, this pin selects the receive monitor gain for receiver n (n=1 or 2)
0= 0 dB
1= 26 dB
LPn[1:0]: Loopback mode select (per channel control)
When the chip is configured by hardware, these pins are used to select loopback operation modes for channel n (Inband loopback
is not provided in hardware control mode).
00= no loopback
01= analog loopback
10= digital loopback
11= remote loopback
THZ: Transmitter Driver High Impedance Enable (global control)
This signal enables or disables both of the transmitter drivers. A low level on this pin enables both of the two drivers while a high
level on this pin places both of the two drivers in high impedance state.
RCLKE: the active edge of RCLKn select when hardware control mode is used (global control)
0= select the rising edge as active edge of RCLKn
1= select the falling edge as active edge of RCLKn
