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 fiber backbone infrastructure. By using a high-frequency fundamental crystal together with the company’s Pluto temperature compensation technology, the CFPT-9400 range is designed to eliminate reception slips that compromise the bandwidth of SDH/SONET and Gigabit Ethernet fiber networks. The device is said to achieve jitter performance of less than 3 ps rms 10 Hz to 80 MHz by avoiding the use of of a phase locked loop in favor of a low-phase noise HFF (high-frequency fundamental) crystal and harmonic multiplication. The HFF crystal is coupled through a SAW filter, suppressing any sub-harmonics of the operating frequency to typically less than -55 dBc. Supply voltage is 3.3V with a low current consumption of 65 mA typical, and output is 3.3V PECL (LVPECL) compatible. The product is packaged as an industry standard 14 mm × 9 mm SMD. It is designed for lead-free soldering, and it is compliant with all requirements of the RoHS regulations.
