This document is about EB52F5 series temperature compensated crystal oscillator (TCXO) information
The EB52F5 series is a temperature‑compensated crystal oscillator (TCXO) designed for applications requiring high frequency stability across a wide temperature range. It operates from a 3.3 V supply and offers selectable frequency ranges from 1.544 MHz up to 44.736 MHz.
Key features include ±1.5 ppm stability, 90 % logic‑high and 10 % logic‑low output levels, 6 ns maximum rise/fall time, 15 pF HCMOS load capability, and low phase noise (‑145 dBc/Hz at 100 kHz offset). The device meets MIL‑STD mechanical and environmental specifications.
