EM38K ULTRA-LOW CURRENT TCXO

14 pin Dual-in-Line compatible TCXO

Highly stable CMOS TCXO with ultra-low supply current

Industry-standard package

Consumes less than 4mA at 20.0MHz with 3.3V supply

Low phase noise

RoHS compliant

DESCRIPTION

OUTLINES AND DIMENSIONS

EM38K TCXOs and VCTCXOs are packaged in a 14 pin DIL

compatible package. The part offers the stability of a TCXO and the

design convenience of HCMOS output with ultra-low current

consumption.
