High frequency clock oscillators

Precision Devices (PDI) has launched two clock oscillators. The OC7A operates with a frequency above 1GHz. The OC7A oscillator supports an operating frequency range of 10.9MHz to 1.17GHz. The new OC5A supports an operating frequency range of 25MHz to 350MHz. These oscillators support a wide range of applications requiring high frequency tolerance, low jitter – RMS 0.6ps and low DC power consumption of less than 95mA. These devices are suitable for high frequency networking and communications systems such as Ethernet, Fibre Channel, WiMAX and wireless applications. To ensure a true square wave output at high operating frequencies both clock oscillators feature a LV-PECL output stage. An LVDS version of both oscillators is also available which supports an operating frequency up to 270MHz for the OC5A and 800MHz for the OC7A. Both clock oscillators have a standard operating temperature range of 0°C to 70°C with a wide operating temperature of -40°C to +85°C available as an option. Both devices are available in a compact six pad ceramic surface mount package. The OC7A has dimensions of 7.0x5.0x1.87mm and the OC5A has dimensions of 5.0x3.2x1.4mm.
