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-profile, 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 standard 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 soldering. Units are available on tape-and-reel at no additional charge. The reel size is 2000 pcs. and is compatible with EIAJ-1009B standards. The low-cost, miniature units are ideal for wireless handsets, PCMCIA applications, and GPS receivers.

Units are available on Tape and Reel at no additional charge when ordering a complete reel. The reel size is 2000 pcs and is compatible with EIAJ-1009B standards. The suggested reflow profile is shown below. The TCXO may be reflowed two times. Frequency shift as a result of reflow will be <1.0PPM. Units should not be adjusted to center frequencies until at least 2 hours after reflow to allow the crystals to stabilize. 0.47 (11.8) max Frequency adjust access Terminal #1 identifier The OSC footprint is compatible with many of the previous generation 6 pin leaded TCXO s. Our OSE model is the same size as the OSC except it provides the two additional pads to match pad connections of 6 pin leaded TCXO s and VCTCXO s. 0.09 (2.2) max 0.055 (1.4) 2 places 0.020 (0.5) 0.050 (1.3) 4 places 4 1 0.025 (0.7) 4 places TCXO s are precision subsystems with tolerances measured to Non-hermetically sealed TCXO s should not be subjected to a wash process that will immerse the TCXO in solvents.
