New EX‑423 Evacuated Miniature Crystal Oscillator for Critical Timing in Low- and Battery-Powered Applications

Microchip Technology announced the EX-423 Evacuated Miniature Crystal Oscillator (EMXO) on May 14, 2026, as a compact timing solution for high-stability & reliability applications.
The device features a low-profile 13 mm x 13 mm package & builds upon the existing EX‑421 portfolio to support space- & power-constrained designs.
It utilizes an ultra-high vacuum seal for thermal insulation & a four-point quartz mount to enhance shock survivability & reduce g-sensitivity.
Target applications include GPS/GNSS tracking, military radios, medical devices, Ocean Bottom Node seismic systems, test equipment, & satellite communications.
Key performance specifications include ultra-low phase noise, tight temperature control, strong short-term stability, fast warm-up, & operation within a 10–20 MHz range.
Power consumption is 1W during warm-up & drops to 0.2W at +25 °C in steady state to extend battery life.
The EX-423 EMXO is available for purchase immediately, with technical support accessible via Microchip Sales Representatives or email at VOP-Support@microchip.com.
