EM53S - OUTLINES AND DIMENSIONS

DESCRIPTION

EM53 series TCXOs are ceramic SMD TCXOs packaged in an industry-

standard, micro-miniature 5 x 3.2mm 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)
