The SiT9371 is a differential MEMS oscillator engineered for low-jitter applications requiring a 100 MHz PCIe clock frequency. The device also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for an external dedicated LDO. The SiT9371 can be factory programmed any combinations of frequency stability, voltage, output signaling (LVDS, LVPECL, HCSL, LP-HCSL), within the device's wide operating range. Programmability enables designers to optimize clock configurations while eliminating long lead times and customization costs associated with quartz devices where each combination is custom-built.
