DESCRIPTION
DATA SHEET
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 50Ω 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.
