Description
The GO1555 is a self contained, miniature Voltage
Controlled Oscillator (VCO). It produces a clean
1.485GHz reference clock signal with low spurious
noise content. It is designed to drive 50Ω strip lines.
The VCO requires a single 2.5V supply and draws a
maximum of 8mA of current. It is packaged in a
miniature 8-pin proprietary surface mount package and
operates over the temperature range of -40°C to +85°C.
The GO1555 can be used in place of the older GO1525
VCO. Compared to the GO1525, the GO1555 saves
space, consumes less power and achieves better jitter
performance.
Note: Optimal performance of the GO1555 is achieved
using slightly different loop bandwidth component
values than those used with the GO1525.
This component and all homogeneous subcomponents
are RoHS compliant.
