Description
The GO1525 is a self contained, miniature Voltage
Controlled Oscillator (VCO). It produces a clean
VCTR
GO1525 HD-LINX™II
Voltage Controlled Oscillator
GO1525 Data Sheet
1.485GHz reference clock signal for the GS1560 and
GS9060 deserializers, and for the GS1532 and
GS9062 serializers. The control voltage range is from
1.0 volts to 1.5 volts and is derived from the on-chip
PLLs. The GO1525 frequency can be pulled
approximately 32MHz for every one volt of control.
The output level is typically -9.0dBm with low spurious
and noise content. It is designed to drive 50Ω strip lines.
The VCO requires a single 2.5V 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.
This component and all homogeneous subcomponents
are RoHS compliant.
