Oscillators for Industrial Timing

Harsh Environment

The PX-702 is a small-footprint, ceramic SMD High-Temperature Crystal Oscillator (HTXO) for extreme environment applications. In addition to its wide operating temperature range, the PX-702 HTXO is also excellent for high shock and vibration applications. The PX-702 HTXO exceeds the 3000g shock and 36g vibration levels of the demanding MIL-STD-883 requirements.

High Temperature

The PX-570 is an HTXO for extreme environment applications. Its typical operating temperature range is from −55°C to +230°C with a frequency stability of ±250 ppm over the entire operating temperature range. 

Real-Time Clock

The HM-4201 is a high-temperature real-time clock and calendar module with a built-in 32.768-KHz Crystal Oscillator (XO). The I²C bus can set timing, calendar and alarm functions and the entire module is fully operational from 2.7V to 3.6V. The timing and calendar functions are operational down to 1.8V range.

Low Power

The EX-421 is the latest addition to our Evacuated Miniature Crystal Oscillator (EMXO) product family. This device delivers exceptional tight temperature stabilities and low aging rates with reduced power consumption (0.25W) to support applications over a wide range of environmental conditions in a 13 mm × 13-mm footprint.
