Renesas Electronics Corporation Programmable Timers and Oscillators 8N4QV01KG-0051CDI

The 8N4QV01KG-0051CDI 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® NG technology, ensuring high clock frequency and low phase noise performance. It supports an absolute pull-range (APR) programmable from ±4.5ppm to ±754.5ppm and includes an I2C interface for programming the output frequency and internal PLL control registers. The device is designed to operate within an extended temperature range of -40°C to 85°C, making it suitable for applications in wireless infrastructure, telecommunications, and networking equipment. The RMS phase jitter at 156.25MHz is specified at 0.494ps (typical) for a bandwidth of 12kHz to 20MHz.
