GO1525 HD-LINX™II
Voltage Controlled Oscillator
GO1525 Data Sheet
Key Features
•
generates 1.485GHz or 1.485/1.001GHz signal for
HD-LINX™II ICs
•
low current consumption
•
50Ω output impedance
•
operates from a single 2.5V supply
•
8 pin tape on reel
•
Pb-free and RoHS Compliant
The output level is typically -9.0dBm with low spurious
and noise content. It is designed to drive 50Ω strip lines.
VCO for the GS1560, GS1559 and GS9060
Deserializers, and the GS1532, GS1531 and
GS9062 Serializers
This component and all homogeneous subcomponents
are RoHS compliant.
Description
GO1555 for new designs
The GO1525 is a self contained, miniature Voltage
Controlled Oscillator (VCO). It produces a clean
1.485GHz reference clock signal for the GS1560 and
GS9060 deserializers, and for the GS1532 and
The GO1555 should be used for new designs given that
it is smaller, consumes less power and gives better jitter
performance.

FOR NEW DESIGNS USE GO1555
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.
Applications
•
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.
