Voltage Controlled Crystal Oscillators
Vectron International 267 Lowell Road, Hudson, NH 03051 Tel: 1-88-VECTRON-1 Web: www.vectron.com
Description:
The VC-800 Voltage Controlled Crystal Oscillator
(VCXO) is a quartz stabilized square wave generator
with a CMOS output and is tested at CMOS and TTL
logic levels (5 volt operation).
Features:
Worlds Smallest VCXO, 3.2 x 5.0 x 1.5mm
Frequencies to 51.84 MHz
5 or 3.3 V operation
Tri-State Output
Low jitter < 6ps rms (output frequencies >12 MHz)
VCXO with CMOS outputs
0/70 or -40/85 °C temperature range
Hermetically sealed ceramic SMD package
VC-800
Performance Characteristics
1. A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended.
2. Symmetry is defined as (ON TIME/PERIOD with Vs = 1.4 V for TTL and Vs=2.5 V for CMOS, 5 volt operation, and
Vs=1.65V for 3.3 Volt operation.
