Renesas Electronics Corporation Clock/Timing - Programmable Timers and Oscillators 8N4Q001LG-0156CDI8

The IDT8N4Q001 is a Quad-Frequency Programmable Clock Oscillator designed for high precision and flexibility in frequency programming. Utilizing IDT,Äôs FemtoClock¬Æ NG technology, it offers low phase noise performance and operates within a supply voltage 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 I¬=C 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¬8C to 85¬8C, making it suitable for applications in wireless infrastructure, telecommunications, and networking equipment. The typical RMS phase jitter at 156.25MHz is 0.253ps for the 12kHz to 20MHz bandwidth, indicating high stability in clock output.
