SiT9397 Datasheet | SiTime

SiT9397 PRELIMINARY AEC-Q100, 220 MHz to 920 MHz Ultra-Low Jitter Differential XO for Automotive Description The SiT9397 is an AEC-Q100 qualified, ultra-low jitter differential oscillator engineered for automotive applications. It delivers the most stable timing under environmental stressors such as shock, vibration, high heat, rapid thermal transients and power supply noise. The SiT9397 can be factory programmed for specific binations of frequency, stability, output signaling, voltage, and output enable functionality. Programmability enables automotive system designers to qualify the device once and use it for different applications. It also eliminates the long lead times and customization costs associated with quartz devices where each bination is custom built. In addition to standard differential signal types, this device es with a unique FlexSwing™ output-driver that performs like LVPECL but provides independent control of voltage swing and DC offset. It is designed to interface with chipsets having non-standard input voltage requirements and eliminate all external source-bias resistors. It also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for an external dedicated LDO.
