Renesas Electronics Corporation Programmable Timers and Oscillators 8N4QV01LG-0169CDI

The 8N4QV01LG-0169CDI 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 supports an extended temperature range of -40¬8C to 85¬8C, making it suitable for applications in wireless infrastructure, telecommunications, and networking equipment. The device includes four default power-up frequencies that can be reprogrammed via an I2C interface, along with control inputs for output enable and frequency selection. The RMS phase jitter at 156.25MHz is specified at 0.494ps (typical) for a bandwidth of 12kHz to 20MHz.
