Description

■

* Depending on frequency and output type

Frequency Adjustment

■

A highly versatile series of surface mountable

14.7 x 9.2 x 6.2mm temperature compensated voltage

controlled crystal oscillators (TCVCXOs) for applications

where small size and high performance are pre-

requisites. This oscillator uses C-MAC’s latest custom

ASIC "Pluto", a single chip oscillator and analogue

compensation circuit, capable of sub 0.3 ppm

performance. Its wide frequency range, operating

temperature range, drive capability, coupled with its

high stability and linear frequency pulling make it the

ideal reference oscillator. Its ability to function down to

a supply voltage of 2.4V and low power consumption

makes it particularly suitable for mobile applications

Three options with external Voltage Control applied to

pad 1:

A - Ageing adjustment: > ±5ppm (Standard Option)

B - No frequency adjustment. Initial calibration @ 25°C

< ±0.5 ppm

C - High Pulling ±10ppm to ±50ppm can be available

depending on frequency and stability options.

For manual frequency adjustment (HCMOS/ACMOS output

only) connect an external 50kΩ potentiometer between

pad 5 (Reference Voltage) and pad 3 (GND) with wiper

connected to pad 1 (Voltage Control). Please specify

reference voltage as a part of the ordering code
