Renesas Electronics Corporation Clock/Timing - Programmable Timers and Oscillators 8N4Q001LG-1095CDI8

The IDT8N4Q001 is a Quad-Frequency Programmable Clock Oscillator designed for high precision and flexibility in frequency programming. Utilizing fourth generation FemtoClock® NG technology, it offers low phase noise performance and operates with supply voltages of 2.5V or 3.3V. The device is housed in a compact 10-lead ceramic package measuring 5mm x 7mm x 1.55mm and is compliant with RoHS standards. This oscillator can be programmed via an I²C interface to output clock frequencies ranging from 15.476MHz to 866.67MHz and from 975MHz to 1,300MHz, with a frequency resolution of 435.9Hz divided by N. It features four default power-up frequencies selectable through FSEL0 and FSEL1 pins, which can also be reprogrammed. The device supports an extended temperature range of -40°C to 85°C, making it suitable for applications in wireless infrastructure, telecommunications, and networking equipment. The typical RMS phase jitter at 156.25MHz is 0.253ps (12kHz - 20MHz) and 0.263ps (1kHz - 40MHz), indicating its reliability for high-performance timing applications.
