Renesas Electronics Corporation Programmable Timers and Oscillators 8N4QV01KG-0100CDI8

The IDT8N4QV01KG-0100CDI8 is a Quad-Frequency Programmable VCXO designed for high precision and flexibility in clock frequency generation. It operates within a frequency range of 15.476MHz to 866.67MHz and from 975MHz to 1,300MHz, with a programming resolution of 435.9Hz divided by N, where N is the PLL output divider. The device utilizes IDT's fourth generation FemtoClock¬Æ NG technology, ensuring low phase noise performance. This VCXO accepts a supply voltage of either 2.5V or 3.3V and is housed in a compact 10-lead ceramic package measuring 5mm x 7mm x 1.55mm. It features four default power-up frequencies that can be selected via FSEL0 and FSEL1 pins, and it supports reprogramming through an I2C interface for output clock frequency adjustments, absolute pull-range settings, and internal PLL control. The device is suitable for applications in wireless infrastructure, telecommunications, and networking equipment, with an operating temperature range of -40¬8C to 85¬8C. The typical RMS phase jitter at 156.25MHz is 0.494ps (12kHz to 20MHz) and 0.594ps (1kHz to 40MHz).
