■Please contact our sales office for current leadtimes
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
RoHS compliance
■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).

A - Ageing adjustment: > ±5ppm, frequency < 20MHz
(Standard Option)
>±7ppm, frequency > 20MHz
B - No frequency adjustment initial calibration @ 25°C
<±1.0 ppm
