Renesas Electronics Corporation Programmable Timers and Oscillators 8N4QV01FG-0077CDI8

The IDT8N4QV01FG-0077CDI8 is a quad-frequency programmable voltage-controlled crystal oscillator (VCXO) designed for high precision and flexibility in clock frequency programming. It operates within a frequency range of 15.476MHz to 866.67MHz and from 975MHz to 1,300MHz, with a frequency step size of 435.9Hz divided by N, where N is the PLL output divider. The device supports an absolute pull range (APR) that can be programmed from ¬±4.5ppm to ¬±754.5ppm, making it suitable for various applications in wireless infrastructure, telecommunications, and networking equipment. The VCXO can be powered by either a 2.5V or 3.3V supply and features a small, lead-free (RoHS 6) 10-lead ceramic package measuring 5mm x 7mm x 1.55mm. It includes four default power-up frequencies selectable via FSEL0 and FSEL1 pins, and it can be programmed through an I2C interface for output clock frequency and internal PLL control. The device exhibits low phase noise performance, with typical RMS phase jitter of 0.494ps at 156.25MHz over a bandwidth of 12kHz to 20MHz. The operating temperature range is specified from -40¬8C to 85¬8C, ensuring reliability in diverse environmental conditions.
