SiT8918中文资料1 to 110 MHz, High Temperature Oscillator (-40 to +125°C)数据手册SiTime规格书

描述 Description

The SiT8918B provides a perfect combination of wide frequency range (1 MHz to 110 MHz), excellent stability (±20 ppm) and wide temperature range (-40 to 125 °C) in the smallest 2.0x1.6 mmxmm package that is not readily available from quartz. This device also features the industry's best shock and vibration resistance.

The SiT8918 comes in industry-standard packages and footprints, and therefore replaces quartz without any design changes.
