C-MAC’s high-frequency TCVCXOs have a stability of 1.5 ppm at 622 MHz and above

C-MAC MicroTechnology has launched a range of low-jitter high-frequency TCVCXOs (temperature compensated, voltage controlled crystal oscillators) for use in TDM (time division multiplexing) switching systems for optical fibre backbone infrastructure. By using a high-frequency fundamental crystal together with C-MAC’s Pluto temperature compensation technology, the new CFPT-9400 range is designed to eliminate reception ‘slips’ that compromise the effective bandwidth of SDH/SONET and Gigabit Ethernet fibre networks.
