Agilent VTO-0995-SMA,
VTO-1070-SMA
Voltage Controlled Oscillator
Data Sheet
Features
• Operating frequency:
9.95328 GHz or 10.754 GHz
• Output power (50Ω load):
2 dBm minimum
Description
The VTO-0995-SMA/
VTO-1070-SMA 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.
Functional Block Diagram
• Modulation sensitivity:
5 to 10 MHz/V
• Tuning voltage:
0 to 10 Volts
Amp
Output
• Low jitter (Less than 50 femto
seconds from 50 KHz to 80 MHz)
• Frequency drift over 0°C to +75°C:
20 MHz
• 1.180" x 0.950" x 0.400"
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 through a filter to the
output.
Applications
• Transmitter and receiver subsystems for OC-192/STM-64
applications
• 10 GHz source
