agilent VTO-0995-to8 voltage controlled oscillator data sheet description the VTO-0995-to8 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 hyper- abrupt varactor diode to provide the tuning capability. the oscilla- tor output is then coupled through a filter to the output. features operating frequency: 9.95328 ghz output power (50 ? load): 2 dbm minimum modulation sensitivity: 5 to 10 mhz/v tuning voltage: 0 to 10 volts low jitter (less than 50 femto seconds from 50 khz to 80 mhz) frequency drift over 0 c to +75 c: 20 mhz 0.5" d x 0.18" h applications transmitter and receiver sub- systems for oc-192/stm-64 applications 10 ghz source functional block diagram VTO-0995-to8 absolute maximum ratings [1] parameter units ratings positive supply voltage v 0 to +10 tuning voltage v 0 to +12 operating temperature c -10 to +95 storage temperature c -40 to +130 note: 1. operation of this device in excess of any of these limits may cause permanent damage. output amp
