| VC-TX0-30SM SERIES TEMPERATURE COMPENSATED OSCILLATOR The VC-TXO-30SM is a TCXO (Temperature Compensated Crystal Oscillator) featuring very tight stability over a wide temperature range. The miniature SMD ceramic package measures 5 x 7 x 2.0 mm. The voltage control feature has a frequency control range of 5 ppm. The low profile package is ideal for wireless communications applications. FEATURES * Highly stable output * Voltage Control function * 5 x 7 mm Footprint * RoHS Compliant PART NUMBERING GUIDE "EXAMPLE" SERIES VC-TXO-30SM - FREQUENCY 128 - STABILITY/TEMPERATURE OPTION B Sample Part Number: VC-TXO-30SM-128-B, 128=12.8 MHz, B= 2.0 PPM -20 +75C STANDARD FREQUENCIES 12.60, 12.80, 13.00, 14.40, 14.85, 16.80 19.20, 19.44, 19.68 & 19.80 MHZ OPERATING CONDITIONS/ELECTRICAL CHARACTERISTICS PARAMETERS FREQUENCY RANGE FREQUENCY TOLERANCE (OPTION A) (OPTION B) CONDITIONS TYPICAL @+25 2C OPER.
