ECS-327TXO SMD 32.768 kHz TCXO

The ECS-327TXO series temperature compensated crystal oscillator (TCXO) is offered in a wide frequency range.

The ECS-327TXO is a 32.768 kHz low-power, temperature compensated crystal oscillator (TCXO). The compact ceramic package 3.28 x 2.5 x 1.3 mm LWH uses an industry-standard footprint. The ±5 ppm stability over -40°C ~ +85°C improves local clock accuracy versus an uncompensated tuning fork crystal.
