## Description

The ECS-200-CDX-0914 is a 20.000 MHz AT-cut quartz crystal resonator in the CSM-3X surface-mount package, measuring 7.0 mm x 4.1 mm. It operates in the fundamental mode with a specified load capacitance (CL) of 10 pF. Key electrical parameters include a frequency tolerance of ±10 ppm maximum at +25°C and a frequency stability of ±30 ppm maximum over the -40°C to +85°C range. The crystal has a maximum equivalent series resistance (ESR) of 50 Ω, a maximum shunt capacitance of 7 pF, and a maximum recommended drive level of 500 µW. The device
