Agilent VTO-8951 Voltage Controlled Oscillator
Data Sheet
Features · Operating frequency: 9.50 to 11.0 GHz · Output power (50 Load): 10 dBm minimum · Modulation sensitivity: 150 to 250 MHz/V Description The VTO-8951 provides a fundamental, low jitter source as a key component for the data re-timing in the transmitter subsystem and clock and data recovery in the receiver of the 10 Gb fiber optic systems. The oscillator uses an extremely high performance low noise Agilent Silicon Bipolar transistor in conjunction with a hyperabrupt varactor diode to provide the tuning capability. The oscillator output is then coupled to through a bandpass filter to the output. Functional Block Diagram · Tuning voltage: 0 to 10 Volts · Low jitter
