ECS-327ATQMV MultiVolt Oscillator

ECS-327ATQMV MultiVolt™ crystal oscillator lets designers use the same device for many applications, reducing qualification requirements and inventory.

ECS-327ATQMV is a 32.768 kHz low-power, AEC-Q200 qualified, MultiVolt™ SMD crystal oscillator. The compact ceramic package 3.2 x 2.5 x 0.9 mm (LWH) uses an industry standard footprint. The MultiVolt feature allows customers to use the same device for many designs, reduce qualification requirements, and reduce inventory.

September 2022 Update 

ECS has expanded the AEC-Q200 qualified ECS-327ATQMV MultiVoltTM oscillator family to include two additional part numbers to cover more applications. The two new part numbers are ECS-327ATQMV-BP-TR that offers ±50ppm stability at -40ºC ~ 105ºC and ECS-327ATQMV-CN-TR that offers ±25ppm stability at -40ºC ~ 85ºC.
