HD-LINX GO1515
Voltage Controlled Oscillator
DATA SHEET
FEATURES
DESCRIPTION
The GO1515 is
• generates 1.485GHz or 1.485/1.001GHz signal for
HD-LINX™ ICs
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.
• low current consumption
• 50Ω output impedance
• operates from a single 5V supply
• 8 pin tape on reel
APPLICATIONS
The output level is approximately 1.0dBm with low spurious
and noise content. It is designed to drive 50Ω strip lines.
VCO for the following HD-LINX™ ICs: GS1515, GS1522,
GS1540, GS1545.
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.
