product data sheet osc series ultra miniature tcxo s features low cost 3.0 or 5.0 vdc option reflow solderable <2.2 mm height voltage tune option applications wireless handsets, pcs, gsm, cellular pcmcia applications gps description vectron international has introduced a series of low-pro- file, low cost, surface mount, temperature compensated crystal oscillators (tcxos) available in frequencies from 10 mhz to 50 mhz. the osc series low-profile (0.09 inch maximum height), surface mount tcxos can be mounted using the stan- dard convection reflow process. the units feature a ppm frequency vs. temperature characteristic over a to operating range and operate from a 3.0v or 5v supply. current drain <2.0 ma. aging <1ppm/year and phase noise is -125 dbc/hz at 100 hz and -150 dbc/hz at 100 khz. the osc series of tcxos and tcvcxos has been designed for pick-and-place mounting and reflow sol- dering. units are available on tape-and-reel at no addi- tional charge. the reel size is 2000 pcs. and is compati- ble with eiaj-1009b standards. the low-cost, miniature units are ideal for wireless handsets, pcmcia applica- tions, and gps receivers.
