RDINP
RDINN
Differential
PECL
Serial Data Input: These built-in line receiver inputs are connected to the differential
receive serial data stream. An internal receive PLL recovers the embedded clock
(RCLK) and data (RDOUT) information.
5
REFCLK
TTL Input
Reference Clock: This input is used as the reference for the internal frequency
synthesizer and the "training" frequency for the receiver PLL to keep it centered in the
absence of data coming in on the RDIN inputs.
26
CD
PECL
Input
Carrier Detect: This input controls the recovery function of the Receive PLL and can be
driven by the carrier detect output of optical modules or from external transition
detection circuitry. When this input is HIGH, the input data stream (RDIN) is recovered
normally by the Receive PLL. When this input is LOW the data on the inputs RDIN will
be internally forced to a constant LOW, the data outputs RDOUT will remain LOW, the
Link Fault Indicator output LFIN forced LOW and the clock recovery PLL forced to look
onto the clock frequency generated from REFCLK.
32
25
DIVSEL1
DIVSEL2
TTL Input
Divider Select: These inputs select the ratio between the output clock frequency
(RCLK/TCLK) and the REFCLK input frequency as shown in the “Reference Frequency
Selection” table.
16
CLKSEL
TTL Input
Clock Select: This input is used to select either the recovered clock of the receiver PLL
(CLKSEL = HIGH) or the clock of the frequency synthesizer (CLKSEL = LOW) to the
TCLK outputs.

LFIN
TTL
Output
Link Fault Indicator: This output indicates the status of the input data stream RDIN.
Active HIGH signal is indicating when the internal clock recovery PLL has locked onto
the incoming data stream. LFIN will go HIGH if CD is HIGH and RDIN is within the
frequency range of the Receive PLL (1000ppm) and will be alternating if not. LFIN is an
asynchronous output.
23
24
RDOUTN
RDOUTP
Differential
PECL
Receive Data Output: These ECL 100K outputs represent the recovered data from the
input data stream (RDIN). This recovered data is specified against the rising edge of
RCLK.

21
RCLKN
RCLKP
Differential
PECL
Clock Output: These ECL 100K outputs represent the recovered clock used to sample
the recovered data (RDOUT).

TCLKP
TCLKN
Differential
PECL
Clock Output: These ECL 100K outputs represent either the recovered clock (CLKSEL
= HIGH) used to sample the recovered data (RDOUT) or the transmit clock of the
frequency synthesizer (CLKSEL = LOW).
