EUROQUARTZ LIMITED Blacknell Lane CREWKERNE Somerset UK TA18 7HE TCXO Clipped Sinewave 5 x 3.2 x1.2mm SMD
DESCRIPTION
EM53 series TCXOs are ceramic SMD TCXOs packaged in an industry- standard, 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). 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 SPECIFICATION Product Series Code TCXO: EM53S VCTCXO: VEM53S Frequency Range: 10.0MHz to 27.0MHz Output Waveform: Clipped Sinewave Initial Calibration Tolerance*: <±1ppm at 25°C Standard Frequencies: 10.0, 12.80, 13.0, 14.40, and 19.68MHz (Partial list) Operating Temperature Range: See table Frequency Stability vs. Ageing: ±1.0 ppm max. first year vs. Voltage Change: ±0.3 ppm max. ±5% change vs. Load Change: ±0.3 ppm max. ±10% change vs. Reflow: ±1ppm max. for one reflow (Measured after 24 hours) Supply Voltage: +2.8, +3.0 or +5.0Volts ( Specify when ordering) Output Voltage Level: 0.8V p-p minimum Start-up Time: 2ms typical, 5ms max. Current Consumption: See table below Output Load: 10kOhm//10pF ±10% Harmonic Distortion: -10dB typical, -7dB max.
