SiT9501 Datasheet

The SiT9501 is a differential MEMS oscillator that is engineered for low-jitter applications requiring standard networking 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 SiT9501 can be factory programmed for specific combinations of frequency, stability, voltage, output signaling, and pin 1 functionality. 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.
