Euroquartz's New VCXO in Mini Surface Mount Package
News Release from:
20 July 2012
Euroquartz is pleased to unveil a new range of voltage controlled crystal oscillators in miniature surface mount packages. The new G534 VCXOs are housed in miniature 5 x 3.2 x 1.2mm SMD packages and are available in the frequency range 625kHz to 50MHz.
The small package size makes these oscillators ideal for use in a wide range of applications including phase-locked loop, SONET/ATM, set-top boxes, MPEG, audio/video modulation, video games consoles and HDTV.
Operating from supply voltages of 3.3 or 5V DC, typical phase jitter for G series VCXOs is less than 1ps. Output logic is HCMOS/TTL and G series VCXOs use fundamental mode crystal oscillators.
Typical specifications include pull range from ±30 to ±100ppm, temperature stability of ±25, ±50 or ±100ppm over two temperature ranges: 0 to 70°C and -40 to +85°C, output load of 15pF (CMOS) or 2 gates (TTL), start up time of 5ms (10ms maximum) and current consumption of 10 to 45mA, frequency dependent. Linearity is 10% maximum, 6% typical while ageing is ±5ppm per year maximum.
Fully RoHS compliant, the new G series VCXOs from Euroquartz are supplied on standard EIA tape and reel and are capable of withstanding reflow soldering conditions of 260°C for 10s maximum (twice) or 230°C for 180s once.
