TCXO
EM57S series VCTCXOs are packaged in the industry-standard 7 x
5mm package. With clipped sinewave output, close tolerances are
available from ±0.5ppm over 0° to 50°C or ±1ppm over -40° to
+85°C. The output is controllable by EFC enabling output variation of
±5ppm to ±12ppm. The part has very low power consumption.
