Overview
EURO QUARTZ EM57K ULTRA-LOW CURRENT TCXO HCMOS 7 x 5 x 2.
5mm SMD Highly stable CMOS TCXO with ultra-low supply current Miniaturized 7 x 5mm SMD package Consumes less than 4mA at 20.
0MHz with 3.
3V supply Low phase noise RoHS compliant DESCRIPTION EM57K TCXOs and VCTCXOs are packaged in a 7 x 5 x 2.
5mm ceramic SMD package.
The part offers the stability of a TCXO and the design convenience of HCMOS output with ultra-low current consumption.
