DATA SHEET

FEATURES

• adjustment-free operation

• auto-rate selection for 5 SMPTE data rates: 143, 177,

270, 360, 540Mb/s

• data rate indication output

• serial data output mute when PLL is not locked

• immune to harmonic locking

• operation independent of SAV/EAV sync signals

• low jitter, low power

• single external VCO resistor for operation with five

input data rates

• large input jitter tolerance: typically 0.45 UI beyond

loop bandwidth

• power savings mode (output serial clock disable)

• system friendly: serial clock remains active when data

outputs muted

• robust lock detect

• Pb-free and Green

APPLICATIONS

The GS9035A is used for Clock and Data recovery, and

Jitter elimination for all high speed serial digital interface

applications

involving

SMPTE

259M

and

other

data

standards.

DESCRIPTION

The GS9035A is a high performance clock and data

recovery IC designed for serial digital data. The GS9035A

receives either single-ended or differential PECL data and

outputs differential PECL clock and retimed data signals.

The GS9035A can operate in either auto or manual rate

selection mode. In auto mode the GS9035A is ideal for

multi-rate serial data protocols such as SMPTE 259M. In this

mode the GS9035A automatically detects and locks onto

the incoming data signal. For single rate data systems, the

GS9035A can be configured to operate in manual mode. In

both modes, the GS9035A requires only one external

resistor to set the VCO centre frequency and provides

adjustment-free operation.

The GS9035A has dedicated pins to indicate LOCK and

data rate. In addition, an internal muting function forces the

serial data outputs to a static state when input data is not

present or when the PLL is not locked. The serial clock

outputs can also be disabled resulting in a 10% power

savings.

The GS9035A is packaged in a 28 pin PLCC and operates

from a single +5 or -5 volt power supply.
