RRCLK_0
O
Received Recovered Output (De-jittered) Clock - channel 0:
Output is the de-jittered or smoothed clock if the jitter attenuator is enabled. The
de-jittered data, RRPOS/RRNEG are clocked to this signal.
If RRCLKES is “low”, RRPOS/RRNEG will be updated at the falling edge of
RRCLK.
If RRCLKES is “high”, RRPOS/RRNEG will be updated at the rising edge of
RRCLK.
5
RRPOS_0
O
Received Recovered Positive Data (De-Jittered) Output - channel 0:
De-jittered positive data output. Updated on the rising or falling edge of RRCLK,
depending upon the state of the RRCLKES input pin (or bit-field setting).
6
RRNEG_0
O
Received Recovered Negative Data (De-Jittered) Output - channel 0:
De-jittered negative data output. Updated on the rising or falling edge of RRCLK,
depending upon the state of the RRCLKES input pin (or bit-field setting).
7
RRCLKES
I
Received Recovered Clock Edge Select Input:
Hardware Mode:
1. When RRCLKES = “0”, then RRPOS and RRNEG are updated on the falling
edge of RRCLK
2. When RRCLKES = “1”, then RRPOS and RRNEG are updated on the rising
edge of RRCLK
NOTE: This applies to all channels.
Host Mode
Connect this pin to GND when the 71D04 is configured in the Host Mode.
Internal 50 K Ohm pull-down resistor.

NC
No Connection
9
Reset
I
Reset Input. (Active-Low):
A high-low transition will re-center the internal FIFO, and will clear the Command
Registers (for Host Mode operation). Resetting this pin may corrupt data within
the device.
For normal operation, pull this pin to VDD.
Internal 50 K Ohm pull-up resistor.

DS3/E3_1
I
DS3/E3 Select Input - channel 1:
This pin along with the STS-1 mode select pin selects the operating mode. The
following table provides the configuration:
