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

When Tri-stated, the output stage is disabled for all
output options, but the oscillator and compensation
circuit are still active (current consumption <1mA)
