No.

Function

RAVS1

Ground

148

The ground (RAVS1) pin for receive clock and

data recovery block reference circuitry. RAVS1

should be connected to a clean ground reference.

RAVD2

Power

145

The power (RAVD2) pin for receive clock and data

recovery block active loop filter and oscillator.

RAVD2 should be connected to a clean, well

decoupled, +5V supply.

RAVS2

Ground

146

The ground (RAVS2) pin for receive clock and

data recovery block active loop filter and oscillator.

RAVS2 should be connected to a clean ground

reference.

RAVD3

Power

140

The power (RAVD3) pin for the RXD+/- and

ALOS+/- PECL inputs. RAVD3 should be

connected to a clean, well decoupled, +5V supply.

RAVS3

Ground

139

The ground (RAVS3) pin for the RXD+/- and

ALOS+/- PECL inputs. RAVS3 should be

connected to a clean ground reference.

RAVD4

Power

141

The power (RAVD4) pin for the RRCLK+/- PECL

inputs. RAVD4 should be connected to a clean,

well decoupled, +5V supply..

RAVS4

Ground

144

The ground (RAVS4) pin for the RRCLK+/- PECL

inputs. RAVS4 should be connected to a clean

ground reference.

Notes on Pin Description:

1. All S/UNI-PLUS inputs and bidirectionals present minimum capacitive loading

and operate at TTL logic levels except for the RXD+/-, ALOS+/-, RRCLK+/-,

and TRCLK+/- inputs which operate at pseudo-ECL (PECL) logic levels.

2. The TXD+/- and TXC+/- outputs have a 6 mA drive capability. The GTOCLK,

GROCLK, RSOC, RDAT[15:0], RXPRTY[1:0], RCA, TCA and D[7:0] outputs

and bidirectionals have a 4 mA drive capability. All other S/UNI-PLUS digital

outputs and bidirectionals have 2 mA drive capability.
