Description

Vectron International has introduced a series of low-pro-file, low cost, surface mount, T emperature Compensated Crystal Oscillators (TCXOs)available in frequencies from 10 MHz to 25 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.

Performance Characteristics

The OSC series of TCXO s and VCTCXO s has been designed for pick and place and reflow sol-dering. Units are available on T ape 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.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 con-nections of 6 pin leaded TCXO s and VCTCXO s.

TCXO s are precision subsystems with tolerances measured to Non-hermeti-cally sealed TCXO s should not be subjected to a wash process that will immerse the TCXO in sol-vents. No clean is the recommended procedure.

PIN 1 = VC or N/C PIN 2 = GROUND PIN 3 = OUTPUT PIN 4 = B+
