| 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 Amp Output * Frequency drift over 0C to +75C: 100 MHz * 0.5" D x 0.18" H Applications * Sonet, FEC and 10 Gbits Ethernet Applications * Industry standard package - hermetic using thin film construction VTO-8951 Absolute Maximum Ratings [1] Parameter Positive Supply Voltage Tuning Voltage Operating Temperature Storage Temperature Units V V C C Ratings 5.2 +15 -10 to +100 -40 to +130 Note: 1. Operation of this device in excess of any of these limits may cause permanent damage.
