SiTime

Precision Timing: System designers rely on SiTime’s semiconductor MEMS programmable solutions to achieve higher performance, smaller size, lower power consumption, and greater reliability. With billions of devices shipped, SiTime is transforming semiconductor timing technology in data centers and at the intelligent edge.

The SiTime Advantage: Automotive, industrial, and telecommunication applications increasingly require higher speeds, lower latency, and distributed computing architectures. SiTime’s ruggedized, programmable timing devices ensure flexibility and high reliability even in the most demanding conditions.

Seamless Timing Integration: The Lattice Semiconductor ORAN Timing and Synchronization Kit integrates the SiT5711A-KW-0009 OCXO to seamlessly support the IEEE 1588 Precision Timing Protocol (PTP). Designed for rapid prototyping and proof-of-concept demos, the Lattice GMII Certus-NX Versa Evaluation Board(G) integrates both the SiT9120A-B120001 differential oscillator and the SiT8925B-13-0001 automotive oscillator to ensure flawless synchronization in harsh automotive and industrial environments.

• SiT5711A-KW-0009 OCXOs: Provides ±5 or ±8 ppb over-temperature stability, 2e-11 ADEV at 10 sec under airflow, and ±40 ppt/°C frequency slope (ΔF/ΔT). Resistant to microphonics and board bending, ideal for outdoor pole-mounted equipment and large telecom PCBs.
• SiT9120A-B120001 Differential Oscillators: Supports 0.6 ps (typ.) integrated RMS phase jitter (12 kHz to 20 MHz), frequency stability from ±10 ppm to ±50 ppm, and a fixed frequency range of 25 to 212.5 MHz.
• SiT8925B-13-0001 Automotive & High-Temp Oscillators: Ensures ±20 ppm frequency stability across a -55°C to +125°C automotive temperature range. Withstands 70 g vibration and 10,000 g shock, featuring configurable drive strength and rise/fall time to minimize EMI.
