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).
