DS3/E3_ch0
I
DS3/E3 Select Input - channel 1
:
See description pin 8.
Internal 50 K Ohm pull-down resistor.
21
DJA0/SCLK
I
Harware Mode
Disable Jitter Attenuator Input - Channel 0:
An active-high disables the Jitter Attenuator. The RPOS/RNEG and RCLK will
be passed through without jitter attenuation.
Host Mode
Microprocessor Serial Interface Clock Signal:
This signal will be used to (1) sample the data, on the SDI pin, on the rising
edge of this signal. Additionally, during “Read” operations, the Microprocessor
Serial Interface will update the SDO output on the falling edge of this signal.
Internal 50 K Ohm pull-down resistor.

RPOS2
I
Received Positive Data (Jittery) Input: - channel 2:
Data that is input on this pin is sampled on either the rising or falling edge of
RCLK depending on the setting of the RCLKES pin (pin 10).
If RCLKES is “high”, then RPOS will be sampled on the falling edge of RCLK.
If RCLKES is “l(fā)ow”, then RPOS will be sampled on the rising edge of RCLK.
Internal 50 K Ohm pull-up resistor.
24
RNEG2
I
Received Negative Data (Jittery) - channel 2:
The input jittery negative data is sampled either on the rising or falling edge of
RCLK depending on the setting of RCLKES.
If RCLKES is “high”, then RNEG will be sampled on the falling edge of RCLK.
If RCLKES is “l(fā)ow”, then RPOS will be sampled on the rising edge of RCLK.
This pin is typically tied to the “RNEG” output pin of the LIU.
Internal 50 K Ohm pull-up resistor.

RCLK2
I
Received Clock (Jittery) - channel 2:
Clock input RCLK2 should be connected to the recovered clock.
Internal 50 K Ohm pull-up resistor.

Digital Ground
28
MCLK2
I
Master Clock Input - channel 2:
Reference clock for internal PLL. 44.736MHz+/-20ppm or 34.368MHz+/-
20ppm. This clock must be continuous and jitter free with duty cycle between
30 to 70%.
It is permissible to use the EXCLK signal orSTS1 clock.
Internal 50 K Ohm pull-up resistor.

DJA2/CS
I
Harware Mode
Disable Jitter Attenuator Input - Channel 2:
See description of pin 25
Host Mode
Chip Select Input:
An active-low input enables the serial interface.
Internal 50 K Ohm pull-down resistor.
