The SiT9375 is a differential MEMS oscillator engineered for low-jitter applications requiring standard frequencies from 25 MHz to 644.53125 MHz. A unique FlexSwing™ output-driver performs like LVPECL but provides independent control of voltage swing and DC offset to simplify interfacing with chipsets having non-standard input voltage requirements and eliminate all external source-bias resistors. The device also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for an external dedicated LDO. The SiT9375 can be factory programmed any combinations of frequency, stability, voltage, output signaling, 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.
