GS1540, GS1545.

DESCRIPTION

The GO1515 is a self contained, miniature Voltage

Controlled Oscillator (VCO) that is used in conjunction with

Gennum’s HD-LINX™ ICs. It produces a clean 1.485GHz

reference clock signal for such devices as the GS1515

HDTV Reclocker and other HD-LINX™ devices. The control

voltage range is from 3.10 volts to 4.65 volts and is derived

from the on-chip PLLs. The GO1515 frequency can be

pulled approximately 16MHz for every one volt of control.

The output level is approximately 1.0dBm with low spurious

and noise content. It is designed to drive 50

Ω strip lines.

The GO1515 VCO is used with the following HD-LINX™ ICs;

GS1515, GS1522, GS1540, GS1545 and is ordered as a

separate item. The VCO requires a single 5V supply and

draws a maximum of 15mA of current. It is packaged in a

miniature 8-pin proprietary surface mount package and

operates over the normal commercial temperature range of

0°C to +70°C.
