EURO QUARTZ EM53S TCXO 5 x 3.2 x 1.2mm SMD Clipped Sinewave 6.4MHz to 40MHz Micro-miniature SMD package 5 x 3.2mm Stability from ±1ppm over -30° to +75°C Supply Voltage from 2.3 Volts to 5.5 Volts Produced as TCXO or VCTCXO with EFC Readily customized EM53S - OUTLINES AND DIMENSIONS DESCRIPTION EM53 series TCXOs are ceramic SMD TCXOs packaged in an industrystandard, micro-miniature 5 x 3.2mm package. This TCXO can be run from a supply voltage of 2.3 to 5.5 Volts. Close tolerances from ±1ppm over -30° to +75°C are available. The part can be produced as either a standard TCXO or a voltage-controlled TCXO (VCTCXO) SPECIFICATION Product Series Code TCXO: VCTCXO: EM53S VEM53S 6.4MHz to 40.0MHz Clipped Sinewave <±1ppm at 25°C 10.0, 12.80, 13.0, 14.40, 15.36, 16.384, 19.2, 19.440, and 19.68MHz (Partial list) Frequency Range: Output Waveform: Initial Calibration Tolerance*: Standard Frequencies: Operating Temperature Range: Frequency Stability vs. Ageing: vs. Voltage Change: vs. Load Change: vs. Reflow: ±1.0 ppm max. first year ±0.3 ppm max. ±5% change ±0.3 ppm max. ±10% change ±1ppm max. for one reflow (Measured after 24 hours) +2.8, +3.0, 3.3 or +5.0Volts ( 0.8V p-p minimum 2ms typical, 5ms max.
