Renesas Electronics Corporation Clock/Timing - Programmable Timers and Oscillators 8N4Q001KG-0126CDI

The IDT8N4Q001KG-0126CDI is a Quad-Frequency Programmable Clock Oscillator designed for high precision and flexibility in frequency programming. Utilizing IDT's FemtoClock® NG technology, it offers low phase noise performance and operates within a frequency range of 15.476MHz to 866.67MHz and 975MHz to 1,300MHz. The device can be powered by either 2.5V or 3.3V and is housed in a compact, lead-free 10-lead ceramic package measuring 5mm x 7mm x 1.55mm. The oscillator features an I²C interface for programming output clock frequencies and internal PLL control registers, allowing for a frequency programming resolution of 435.9Hz divided by N. It includes four default power-up frequencies selectable via 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.
