Euroquartz has introduced three ranges of SMT miniature differential LVDS oscillators, offering femtosecond integrated phase jitter and superior phase noise at a competitive price. HDK3261 series oscillators are housed in 3.2x2.5x1mm surface mount packages and are available in frequencies from 13.5 to 200MHz with typical phase jitter of 200fs and phase noise of -144dBc/Hz at 100kHz.

HDK5361 (5x3.2x1.2mm) and HDK5761 (7x5x1.8mm) oscillators are available from 40 to 200MHz and offer typical phase jitter of 300fs with phase noise of -136dBc/Hz at 10kHz. All three series are available with 2.5 or 3.3V supply voltage offering differential LVDS square wave output.

Specifications include current consumption of 30mA typical, 50mA maximum for HDK3261, 16mA typical, 27mA maximum for HDK5361 and 5761, start-up time of 10ms maximum and ageing of ±3ppm per year maximum for all models. Operating temperature ranges from -10 to +70°C (commercial) and -40 to +85°C (industrial) are available across the range.

Supplied on 16mm tape in quantities of 1000 pieces per reel, the HDK series differential LVDS oscillators suit a wide range of applications including 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.
