HCSL clock oscillators

15 August 2018 Analogue, Mixed Signal, LSI

Euroquartz is now offering high-speed current steering logic (HCSL) versions of its ultra-low phase jitter EQJF clock oscillator range. HCSL outputs deliver a less ‘noisy’ solution compared with static logic types, a major benefit for mixed low-voltage signal processing and essential in applications such as optical communications, PCI Express and Intel chipsets.

Offering a range of frequencies from 50 to 700 MHz with phase jitter of 150 fs typical (300 fs maximum), this new generation of oscillators is produced in the UK and available for delivery in one to two weeks. HCSL offers the fastest switching speeds with power consumption – at 94 mA typical, 115 mA maximum – lying between LVCS and LVPECL types.

EQJF series HCSL oscillators feature a choice of supply voltages – 1,8 V, 2,5 V or 3,3 V – with frequency stability specifications of ±25, ±50 and ±100 ppm over both commercial (-10°C to +70°C) and industrial (-40°C to +85°C) temperature ranges available as standard. Tighter 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 700 MHz with identical options and similar RMS phase jitter performance. Both ranges feature maximum ageing of ±3 ppm in first year (±2 ppm per year thereafter), duty cycle of 50% ±5% and rise times of 0,4 ns maximum. Additional features include start-up time of 5 ms typical (10 ms maximum) and output enable/disable functions.

RoHS compliant, the new oscillators are housed in industry standard 8-pad, 7 x 5 mm surface mount packages capable of withstanding 260°C for 10 seconds, twice.

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.
