GO1555IXTE3

GO1555 Voltage Controlled Oscillator GO1555 Data Sheet Key Features Description Generates 1.485GHz or 1.485/1.001GHz signal for The GO1555 is a self contained, miniature Voltage Gennum ICs Controlled Oscillator (VCO). It produces a clean 1.485GHz reference clock signal with low spurious Low power 20mW less than GO1525 noise content. It is designed to drive 50 strip lines. 50 output impedance The VCO requires a single 2.5V supply and draws a Operates from a single 2.5V supply maximum of 8mA of current. It is packaged in a 8 pin tape on reel miniature 8-pin proprietary surface mount package and Pb-free and RoHS Compliant operates over the temperature range of -40C to +85C. Applications The GO1555 can be used in place of the older GO1525 VCO. Compared to the GO1525, the GO1555 saves Other Products: space, consumes less power and achieves better jitter GS4915 ClockCleaner performance. Deserializers: Note: Optimal performance of the GO1555 is achieved GS1559, GS1560A, GS1561, GS9060 using slightly different loop bandwidth component Serializers: values than those used with the GO1525. GS1531, GS1532, GS9062 This component and all homogeneous subcomponents are RoHS compliant.
