™

The GENLINX GS9010A is a monolithic integrated

GS9000B or GS9000S, the GS9010A:

circuit designed to be an Automatic Tuning Subsystem

(ATS) when used with the GS9005A Receiver or the

GS9015AReclocker andtheGS9000BorGS9000SDecoder.

The GS9010A ATS eliminates the need to manually set or

externallytemperaturecompensatetheReceiverorReclocker

VCO. The GS9010A can also determine whether the

incomingdatastreamis4ƒscNTSC, 4ƒscPALorcomponent

4:2:2.

- constitutes an automatic 'tweakless' Serial

Digital receiving system

- eliminates the need for trim pots and external

temperature compensation for bit rates to 370 Mb/s

- automatically determines whether data is 4ƒsc

or 4:2:2, and whether the 4ƒsc data is NTSC or

PAL

- acquires lock from a 'no signal' condition in typically

50 ms

The GS9010A is an enhanced version of the GS9010. Pin

compatible with the GS9010, the GS9010A offers improved

noise immunity to spurious HSYNC signals.

- holds lock during data interruptions for typically 2s

- relocks from synchronous switching in less than

The GS9010A includes a ramp generator/oscillator which

repeatedlysweepstheReceiver/ReclockerVCO frequency

over a set range until the system is correctly locked. Once

locked, an automatic fine tuning (AFT) loop maintains the

VCO control voltage at its optimum centre point over

variations in temperature. During normal operation, the

GS9000BorGS9000SDecoderprovidescontinuousHSYNC

pulses which disable the ramp/oscillator of the GS9010A.

This maintains the correct Receiver/Reclocker VCO

frequency. When an interruption to the incoming data

stream is detected by the Receiver/Reclocker, the Carrier

Detect goes LOW and opens the AFT loop in order to

maintain the correct VCO frequency for a period of typically

2 seconds. If the signal is re-established within this 2

seconds, the Receiver/Reclocker will rapidly relock. For

periods longer than typically 2 seconds, the VCO slowly

drifts towards a minimum frequency. Typically after 2

minutes, the serial clock output of the PLL settles to

approximately 85 MHz when ƒ/2 is high or 170 MHz

when ƒ/2 is low. The GS9010A is packaged in a 16 pin

wide SOIC, operates from a single +5 or -5 volt supply

and typically consumes 40 mW of power.

10 µs

• 16 pin SOIC packaging

• operates from a single +5 or -5 volt supply

• typically consumes only 40 mW

• immunity to spurious HSYNC inputs

• defines minimum GS9005A VCO frequency after

extended absence of input signal

• matches GS9005A capture range

APPLICATIONS

• 4ƒsc, 4:2:2 & 360 Mb/s serial digital interfaces
