TEMPERATURE-COMPENSATED CRYSTAL OSCILLATORS

EM38S & VEM38S

CLIPPED SINEWAVE TCXO & VCTCXO

PACKAGE OUTLINE

DESCRIPTION

M38 TCXOs incorporate a hermetically sealed crystal designed to provide

a highly stable frequency source with the lowest possible phase-noise and

ageing. The EM38S TCXO has a 3 pin leaded package conforming to the

dimensions of 14 pin dual-in-line and incorporates a mechanical trimmer

for fine frequency adjustment. VEM38S packages are provided with 4 pins

for the purpose of electrical frequency tuning. Available with power supply

from 2.3 Volts to 5.5 Volts.
