RRCLK0
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 “l(fā)ow”, 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
RRPOS0
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 set-
ting).
6
RRNEG0
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 set-
ting).
7
RRCLKES
I
Received Recovered Clock Edge Select Input:
Hardware Mode:
1. When RRCLKES = “0”, then RRPOS and RRNEG are updated on the fall-
ing edge of RRCLK
2. When RRCLKES = “1”, then RRPOS and RRNEG are updated on the rising
edge of RRCLK

OTE
:
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.
8
NC
9
RST
I
Reset Input.
(Active-Low):
A high-low transition will re-center the internal FIFO, and will clear the Com-
mand 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 Select Input - channel 1
:
This pin along with the STS-1 mode select pin selects the operating mode. The
following table provides the configuration:
STS-1
DS3/E3
XRT71D04 Operating Mode
0 0 DS3 (44.736 MHz)
0 1 E3 (34.368 MHz)
1 0 STS-1 (51.84 MHz)
1 1 E3 (34.368 MHz)
Internal 50 K Ohm pull-down resistor.
