TCXO
DESCRIPTION
VEM44S series VCTCXOs are packaged in the industry-standard 11.4
x 9.6 x 4.7mm 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.
