Low jitter oscillators for broadcast use are on quick delivery schedule
Frequency control specialist, Euroquartz offers quick delivery and samples of its latest introduction, low phase jitter oscillators. They have a low phase jitter of 150fs typical, and are produced in the UK. They are available for delivery in as little as one to two weeks.
Applications include flat panel displays for consumer TVs, video streaming systems via external cables (e.g. LDI), high speed serial communications links such as Serial ATA and FireWire, SONET, xDSL, SDH, set-top box and Ethernet cards. Frequencies available range from 50 to 2100MHz with a choice of outputs including LVPECL, LVDS and CML differential. High current steering logic (HCSL) differential outputs are also available for oscillators up to 700MHz.
There are two versions available. The EQJF series oscillators feature a choice of supply voltages, namely 1.8, 2.5 or 3.3V across the range apart from LVPECL models which are 2.5 and 3.3V only. Frequency stability specifications of ±25, ±50 and ±100ppm over both commercial (-10 to +70°C) and industrial (-40 to +85°C) temperature ranges are available as standard. Custom options can be supplied to special order.
Complementing the EQJF series is the EQVJF range of voltage controlled crystal oscillators (VCXOs) offering frequencies from 150 to 2100MHz (HCSL 150 to 700MHz) with identical options and similar RMS phase jitter performance.
Both oscillator ranges feature maximum ageing of ±3ppm in first year (±2ppm per year thereafter), duty cycle of 50 per cent ± five per cent, rise times of 0.35nanoseconds maximum (0.4nanoseconds for HCSL) and current consumption from 70 to 100mA typical depending on output logic selected. Additional features include start-up time of five milli seconds typical, 10milli seconds maximum and output enable/disable functions.
Both the EQJF oscillators and EQVJF VCXOs are RoHS-compliant and housed in industry standard eight-pad, 7.0 x 5.0mm surface mount packages capable of withstanding 260°C for 10 seconds, twice.
