Miniature VCXOs range from 40-170 MHz.

Press Release Summary:

Packaged in 3.2 x 2.5 mm 6-pad ceramic package with hermetically sealed metal lid to reduce EMI radiation, Model IQXV-80 offers LVPECL output while Model IQXV-81 offers LVDS. Both operate from 3.3 V power source and are available with stabilities of ±25 ppm or ±50 ppm over operating temperature range of -40 to 85°C. In either case, frequency can be adjusted externally by application of control voltage (1.65 V ±1.5 V) which can pull output frequency by minimum of ±80 ppm.

New Miniature LVPECL/LVDS VCXOs Launched by IQD at Electronica

With growing demand for high speed data transmission IQD is introducing at Electronica the new IQXV-80 and IQXV-81 series LVPECL/LVDS Voltage Controlled Crystal Oscillators (VCXOs) to their range. Low-Voltage Positive Emitter-Coupled Logic (LVPECL) outputs are typically chosen for their compatibility with high-speed ICs whilst Low Voltage Differential Signalling (LVDS) is similar but with lower power consumption. Intended for applications such as 10G & 40G Ethernet, SDH/SONET, WiMax, WLAN and Digital Imaging, both new models are available in a wide frequency range from 40 to 170MHz.

Packaged in 3.2 x 2.5mm industry standard 6-pad ceramic package, with a hermetically sealed metal lid to reduce EMI radiation. The IQXV-80 offers an LVPECL output while the IQXV-81 offers LVDS. Both series operate from a 3.3V power source and are available with stabilities of ±25ppm or ±50ppm over an operating temperature range of -40 to 85 degrees C. In either case the frequency can be adjusted externally by the application of a control voltage (1.65V±1.5V) which can pull the output frequency by a minimum of ±80ppm. This allows for absolute frequency adjustment and a correction for crystal ageing.

Both variants offer tri-state capability which can aid the testing and isolation of the circuit during alignment and upgrading. Phase jitter is extremely low for devices of this nature at less than 1ps RMS (12kHz to 20MHz). The IQXV-80 and IQXV-81 are available in bulk pack for prototyping and tape & reel for volume production.

Full details will be available at IQD’s stand 314 in Hall B5 at Electronica 2014.
