1 to 220 MHz, AEC-Q100 Ultra-low Jitter 125°C Differential Oscillator for Automotive


The SiT9396 is an AEC-Q100 qualified, ultra-low jitter differential oscillator engineered for automotive applications up to 125°C ambient temperature. It delivers exceptional dynamic performance of 150 fs (typ.) jitter and frequency stability of ±30 ppm in the presence of common automotive environmental stressors such as shock, vibration, rapid thermal transients, and power supply noise. The SiT9396 is available in the industry smallest 2.0 x 1.6 mm package in addition to 2.5 x 2.0 mm and 3.2 x 2.5 mm options. 

The SiT9396 can be factory programmed for specific combinations of frequency, stability, voltage, output signaling, and pin 1 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 combination is custom-built.

This device comes 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.
