Microchip Technology DSA1103/23 Low-Jitter Precision LVDS Oscillators
Microchip Technology DSA1103/23 Low-Jitter Precision LVDS Oscillators are high-reliability timing components tailored for automotive systems that demand low phase noise and robust performance. Built on Micro-Electro-Mechanical Systems (MEMS) technology, these Microchip oscillators deliver ultra-low jitter (typically less than 1ps RMS). Featuring a differential LVDS output, the DSA1103/23 series supports precise signal transmission with minimal electromagnetic interference. These devices are AEC-Q100 Grade 1 qualified, ensuring dependable operation across wide temperature ranges and under conditions of shock and vibration. Programmable frequency options and compact packaging make these oscillators versatile for integration into advanced automotive applications, including advanced driver-assistance systems (ADAS), infotainment systems, and vehicle networking platforms.Features
