Microchip Technology DSA1104/24 Low-Jitter Precision HCSL Oscillators
Microchip Technology DSA1104/24 Low-Jitter Precision HCSL Oscillators are high-performance timing devices engineered for automotive applications requiring exceptional signal integrity and reliability. These Microchip DSA1104/24 oscillators feature a differential HCSL output and are built on Micro-Electro-Mechanical Systems (MEMS) technology, offering ultra-low jitter performance (typically less than 1ps RMS). These features make these oscillators ideal for high-speed data communication systems such as PCIe interfaces. Designed to meet AEC-Q100 Grade 1 standards, the oscillators operate across wide temperature ranges and provide excellent frequency stability under environmental stressors like shock and vibration. Compact packaging and programmable output frequencies enhance design flexibility, while robust performance ensures dependable operation in advanced driver-assistance systems (ADAS), infotainment platforms, and automotive networking environments.Features
