Raltron Electronics Corp. has announced the availability of the VSO9900A series of voltage-controlled SAW device-based oscillators (VCSOs) that offers very low jitter at high frequencies.

Using a SAW device, the VSO9900A series bypasses many multiplication stages needed to attain a high frequency with standard crystal-based designs. The family provides a frequency range from 400MHz to 1GHz with a particular emphasis on typical frequencies used in the optical transmission domain (622.08MHz, 644.531MHz, 669.327MHz, etc.). The series is suitable for applications such as SONET/SDH, base stations, high-speed data transfer, optical transmission and all kinds of PLLs.

The VCSOs, offered in a compact 5mm x 7mm x 2.5mm package, produce a jitter as low as 0.100ps-rms within a bandwidth of 12kHz to 20MHz, phase noise of -150dBc/Hz at 10kHz offset from carrier and an absolute pull range (APR) of ±100ppm. The devices operate on a supply voltage of 3.3V and feature LVDS or LVPECL complementary outputs as well as an Enable/Disable function.
