Saelig launches ultra-low jitter oscillators
Saelig has launched the EQHJ series Oscillators designed by frequency control specialist Euroquartz, offering ultra-low phase jitter. The oscillators provide a precision LVCMOS output from a supply voltage of 1.8, 2.5 or 3.3V.
The EQHJ series oscillators deliver frequency stability from ±25ppm over the whole industrial temperature range of −40 to +85°C. Three industry standard surface mount packages are available – 7.0×5.0x1.4mm, 5.0×3.2×1.2mm and 3.2×2.5×1.0mm. Current consumption ranges from 3mA typical (5mA max.) for the smallest package size to 7mA typical (10mA max.) for the largest devices. The EQHJ series oscillators are available in the frequency range 5.0 to 50MHz. Additional specifications include 15pF load (CMOS), start-up time of 0.8ms typical, 5.0ms maximum and duty cycle of 50% ±5% (measured at 50% VDD). Typical rise times are 5.0ns for smallest size, down to 1.5ns for largest package, with 10ns maximum across all sizes. Aging is ±3ppm for first year and ±2ppm per year thereafter (at 25°C). Phase noise specifications are 48fs typical at 3.3VDD and 118fs typical at 1.8VDD.
Designed for use in applications that require ultra-low phase noise – such as flat panel displays for consumer TVs, video streaming systems via external cables (e.g. LDI), high speed serial communications links such as Serial ATA & FireWire, SONET, xDSL, SDH, set-top box and Ethernet cards, the EQHJ series of oscillators is available now.
The EQHJ series oscillators are made by European frequency product specialist Euroquartz, an independent UK-based manufacturer and supplier of quartz crystals, oscillators, filters and frequency-related products to the worldwide electronics industry. The company is AS9100 registered and designs and manufactures a comprehensive range of frequency control components for a wide range of customers for military and aerospace, communications, general electronics, computing, control systems and petrochemical applications. The EQHJ series high reliability oscillators are available now from Euroquartz’ USA distributor Saelig Company.
