VEM38S - OUTLINES AND DIMENSIONS
DESCRIPTION
VEM38S series TCXOs are packaged in the industry-standard 14 pin
Dual-in-Line package. With Clipped Sinewave output, tolerances are
available from ±1.0ppm over 0° to 50°C to ±1ppm over -30° to
+70°C. Supply voltage 3.0 or 5.0 Volts. The output is controllable by
EFC enabling output variation of ±5ppm to ±12ppm.
