Ultra-low phase noise crystal oscillators for automotive applications

Euroquartz has released a new series of surface mount ultra-low phase noise crystal oscillators created for employment in automotive applications.

Providing a broad operating temperature range from -40C to +125C, the new XOY series features superior phase noise performance of -155dBc/Hz at 10kHz and -160dBc at 100kHz offset. Femtosecond integrated phase jitter is 150fs typical (12kHz to 20MHz) and frequencies possible range from 1.25MHz to 50MHz.

The new automotive-grade components are contained in a 3.2mm x 2.5mm surface-mount package with supply voltages of 1.8V, 2.5V and 3.3V (±10%) available. Further specifications include 15pF LVCMOS load, a maximum rise time of 10ns, maximum start-up time of 5ms and tri-state function as standard. Current consumption is 2mA to 6mA maximum depending on supply voltage and frequency. Ageing is ±2ppm maximum for the first year. Solder profile is 260C max.
