Description
Surface mount temperature compensated voltage controlled
crystal oscillators for medium to high volume applications
where small size and high performance are prerequisites.
Manufactured for us by Rakon utilising their Pluto™ ASIC
technology and 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
