The ECS Inc. International MultiVolt™ quartz-based oscillators utilize a cutting-edge small form factor high-performance ASIC. The oscillator circuit stage uses a low-current linear voltage regulator. This significantly reduces current consumption compared to traditional oscillator designs. This regulation allows MultiVolt™ oscillators to operate over a wide deteriorating battery supply or a traditional fixed supply which all but eliminated the traditional characteristic of oscillator supply voltage dependency.
MultiVolt™ oscillators offer better jitter and phase noise performance compared to SAW or MEMS-based oscillators, and traditionally they do this at a lower cost point. These MultiVolt™ oscillators can serve multiple platforms to aid your design efforts. Most MultiVolt™ oscillator lines will operate across supply voltages of 1.6V ~ 3.6V and on a static supply compatible with 1.8V, 2.5V, 3.0V, and 3.3V. They come in industry standard packages and footprints from 1.6 x 1.2 mm up to 7.0 x 5.0 mm.
ECS Inc. International offers a wide variety of MultiVolt™ oscillator classifications:
- TXO-MV / TXO-CSMV
Standard MultiVolt™ — MV
The ECS Inc. standard MultiVolt™ HCMOS oscillators are the most flexible oscillator parts available on the market today with frequency range options from 32.738 kHz ~ 160 MHz. MultiVolt™ oscillators can operate across supply voltages of 1.6V ~ 3.6V and on a static supply compatible with 1.8V, 2.5V, 3.0V, and 3.3V. These quartz-based oscillators offer better jitter and better performance than MEMS oscillators at a lower cost. They are available in a wide range of industry standard packages with stabilities of ±20ppm, ±25ppm, ±50ppm, or ±100ppm and temperature ranges of -10ºC ~ +105ºC or -40ºC ~ +85ºC.

Choosing a MultiVolt™ Oscillator vs. MEMs Oscillator
When designing in any oscillator, it is important to keep in mind a variety of performance characteristics such as jitter, phase noise, stability, and power consumption. Based on these specific characteristics, quartz-based oscillators will have the advantage over MEMS based oscillators. Traditionally, crystal oscillators have a much lower power consumption, consistently better jitter, lower phase noise, and a much more stable frequency over time.
See below for two case studies from 2020 on MEMS vs. crystal MultiVolt™ oscillators comparing cost and performance advantages.
