RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Fairport, NY, USA: Saelig Company, Inc. (www.saelig.com) has introduced a new series of ultra-miniature voltage-controlled crystal oscillators (VCXO) that use fundamental mode crystals for superior phase-noise performance. Available in frequencies from 1.0 to 50 MHz, the new G326 series VCXOs feature integrated phase jitter of 200 fs (typical) and suit a wide range of timing applications, such as Phase Lock Loops (PLL), SONET, ATM, set-top boxes, MPEG, audio-video modulation, video game consoles and HDTV, ONET, 10GbE, Fiber Channel, wireless repeaters, transponders, FPGAs, data acquisition, etc.
Unlike standard clock oscillators that have a fixed output frequency, the output of G326 VCXOs can be tuned 50 to 200ppm up or down from the nominal frequency by varying a control voltage accessed via a pad on the component. This control voltage operates on a varactor - a voltage variable capacitance tuning diode. So G326 VCXOs are ideal for systems that need to be able to dynamically alter the system clock frequency.
Housed in a low mass, ultra-miniature 6-pad SMD package measuring 3.2 x 2.5 x 1.0 mm, the G326 series VCXOs are available in 1.8, 2.5, 3.3 or 5 V DC supply voltage versions and offer CMOS (15 pF) or TTL (two gates) output. Additional specifications include rise/fall times of 6ns maximum, duty cycle of 50% ±10% (±5% available to order), start-up time within 10ms, current consumption of 10 to 45 mA dependent on frequency, and linearity of 6% typical, 10% maximum.
Available in both commercial (-10 to +70°C) and industrial (-40 to +85°C) operating temperature ranges, the new G326 series of VCXOs is made by European frequency product specialist Euroquartz, an AS9100 registered, independent UK-based manufacturer and supplier of quartz crystals, oscillators, filters and frequency-related products. The G326 series oscillators are available now from Euroquartz' USA distributor Saelig Company. Inc.
