SiT9375 Low Jitter Differential XO for Standard Frequencies PRELIMINARY Description The SiT9375 is a differential MEMS oscillator that is engineered for low-jitter applications requiring standard frequencies from 25 MHz to 644.53125 MHz. In addition to standard differential signal types, a unique FlexSwing™ output-driver performs like LVPECL and provides independent control of voltage swing and DC offset to simplify interfacing with chipsets having nonstandard 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 for specific binations of frequency, stability, output signaling, voltage, and output enable functionality. Programmability enables designers to optimize clock configurations while eliminating long lead times and customization costs associated with quartz devices where each bination is custom built. The wide frequency range and programmability makes this device ideal for munications, enterprise, and industrial applications that require a variety of frequencies and operate in noisy environments.
