A series of Lead Free, surface mountable TCXO /
TCVCXO 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
0.3ppm performance over an extended temperature
range. Its ability to function down to a supply voltage
of 2.4V and low power consumption makes it
particularly suitable for mobile applications.
