EM32S - OUTLINES AND DIMENSIONS

DESCRIPTION

EM32 series TCXOs are ceramic SMD TCXOs packaged in an industry-

standard, ultra-miniature 3.2 x 2.5mm 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).
