DSA2000中文资料Low Jitter Configurable Dual Output Oscillators for Automotive数据手册Microchip规格书

描述 Description

The DSA20xx family of high performance dual output oscillators utilizes proven silicon MEMS technology to provide excellent jitter and stability while incorporating additional device functionality. The two outputs arecontrolled by separate supply voltages to allow for independent voltage level control. The frequencies of the outputs can be identical or independently derived from a common PLL frequency source. The DSA20xx have provisions for up to eight user-defined pre-programmed, pin-selectable output frequency combinations. The DSA20x1 is also equipped with independent pin-selectable output drive strengths for the CMOS output to reduce EMI and noise.
