LVDS oscillator sets the pace for high-data-throughput computer networking applications

Nov. 25, 2008 - PRLog -- IQD Frequency Products has announced the CFPS-60, a new SPXO (simple packaged crystal oscillator) with LVDS output for use in computer networking equipment and peripherals such as switches, hubs, routers and network interface cards.

IQD Frequency Products has announced the CFPS-60, a new SPXO (simple packaged crystal oscillator) with LVDS output for use in computer networking equipment and peripherals such as switches, hubs, routers and network interface cards.

The high-speed, low-power-dissipation characteristics of LVDS (low-voltage differential signalling) suit the CPFS-60 well to applications with very high data throughput. Data integrity is supported by fast signal rise and fall times of just 0.7ns (20% to 80%), compared to typically 5 or 6ns for a low-cost HCMOS SPXO. Phase jitter is suitably low at a maximum of 1ps RMS (12kHz to 20MHz).

The CFPS-60 offers a range of output frequencies from 75.0MHz to 170.0MHz — high for a low-cost device — and frequency stabilities of 25, 50 or 100ppm over operating temperature ranges of –40° to +85°C (industrial) or –10° to +70°C (general purpose). Shock and vibration qualification to Mil-Std-202F allows for use in both industrial environments and portable equipment.

The CFPS-60 comes as a 7 x 5mm SMD and can be supplied in tape-and reel format for automatic placement. It operates from a 3.3V supply and has tristate functionality as standard.
