Description
■
A series of surface mountable 7.0
×
5.0mm temperature
compensated voltage controlled crystal oscillators
(TCVCXOs) for medium to high volume 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 1 ppm
performance over an extended temperature range. Its
ability to function down to a supply voltage of 2.4V and
low power consumption make it particularly suitable for
mobile applications

Parts with the suffix ‘LF’ on the ordering code and part
number are fully compliant with the European Union
directive 2002/95/EC on the restriction of the use of
certain hazardous substances in electrical and
electronic equipment. Note: The RoHS compliant parts
are suitable for assembly using both Lead-free solders
(see Lead-free Reflow soldering profile) and Tin / Lead
solders (see Tin / Lead Reflow soldering profile).
Three options with external Voltage Control applied to
pad 10:
A - Ageing adjustment: > ±5ppm, frequency < 20MHz
(Standard Option)
> ±7ppm, frequency > 20MHz
B - No frequency adjustment initial calibration @ 25°C
< ±1.0 ppm
C - High Pulling ±10ppm to ±50ppm can be available
depending on frequency and stability options.
