The CMR200T-32.768KDZB-UT is a 32.768kHz CMOS-output crystal oscillator in an ultra-small 2.0 x 1.2mm ceramic SMD package. Unlike a bare crystal that requires an external oscillator circuit, this device integrates the crystal and oscillator amplifier, providing a direct CMOS clock output. The 3.3V supply and low current consumption make it ideal for RTC clocking in battery-backed systems.<\/p>\n

Unlike bare crystals that require an external oscillator circuit with careful PCB layout and load capacitor selection, this device integrates the 32.768kHz tuning-fork crystal and CMOS oscillator amplifier in a single hermetically sealed package. The result is a plug-and-play clock source that simply requires VCC, GND, and produces a clean CMOS square wave output. The 3.3V supply voltage matches the logic levels of modern ARM Cortex-M and other popular MCU families. The ultra-small 2.0 x 1.2mm footprint is ideal for space-constrained wearable and IoT designs.","working_principle":"The CMR200T integrates a 32.768kHz tuning-fork crystal and a CMOS oscillator circuit in a single hermetically sealed ceramic package. The internal oscillator amplifier drives the crystal at resonance and converts the sinusoidal oscillation to a CMOS-compatible square wave output. The integrated design eliminates the need for external load capacitors and ensures reliable oscillator startup across the entire temperature and voltage range, removing a common source of design failures with discrete crystal circuits.","pin_description":"
