Renesas Electronics Corporation Programmable Timers and Oscillators 8N4QV01KG-1120CDI

The 8N4QV01KG-1120CDI is a Quad-Frequency Programmable VCXO from Quarktwin Technology Ltd. It features flexible frequency programming capabilities, allowing output clock frequencies to be set between 15.476MHz to 866.67MHz and from 975MHz to 1,300MHz with a precision frequency step size of 435.9Hz divided by N. The device operates on 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. The VCXO utilizes fourth generation FemtoClock¬Æ NG technology, ensuring high clock frequency and low phase noise performance. It includes four default power-up frequencies that can be selected via FSEL0 and FSEL1 pins, and it supports reprogramming through an I2C interface for output frequency, absolute pull-range (APR), and internal PLL control registers. The APR is programmable from ¬±4.5ppm to ¬±754.5ppm, and the device operates within an extended temperature range of -40¬8C to 85¬8C, making it suitable for applications in wireless infrastructure, telecommunications, and networking equipment. The RMS phase jitter at 156.25MHz is specified as 0.494ps (typical) for a bandwidth of 12kHz to 20MHz.
