The SiT1630AI-H4-DCC-32.768E is an Ultra-Small SMD Oscillator (XO) manufactured by SiTime. It is a reduced power, 32.768 kHz Crystal Oscillator (XO) with SMD Package size 2012-4 and RoHS compliance. It has low jitter of 0.8 ps max, low EMI and low Aging for low power applications, and is one of the smallest devices available in the industry. The oscillator is capable of very low, stable operation, which is ideal for applications such as low power mobile devices, energy harvesting, and battery powered systems. It operates over the industry standard temperature range of -40 to + 85°C, allowing for stable operations in a broad range of industrial and consumer applications. The SMD Oscillator (XO) is designed to meet the stringent requirements for space-constrained applications, with a footprint that is less than 17% of the size of a standard 14-pad oscillator device.
