Renesas Electronics Corporation Clock/Timing - Programmable Timers and Oscillators 8N4QV01KG-0077CDI8

The IDT8N4QV01KG-0077CDI8 is a Quad-Frequency Programmable VCXO that offers flexible frequency and pull-range programming capabilities. Utilizing IDT's fourth generation FemtoClock¬Æ NG technology, it provides high clock frequency with low phase noise performance. The device operates with a supply voltage of either 2.5V or 3.3V and is housed in a compact, lead-free 10-lead ceramic package measuring 5mm x 7mm x 1.55mm. This VCXO can be programmed via an I2C interface to output clock frequencies ranging from 15.476MHz to 866.67MHz and from 975MHz to 1,300MHz, with a frequency step size of 435.9Hz divided by N. It supports four default power-up frequencies selectable through FSEL0 and FSEL1 pins, which can also be reprogrammed. The device is designed to operate within an extended temperature range of -40¬8C to 85¬8C, making it suitable for applications in wireless infrastructure, telecommunications, and networking equipment. The typical RMS phase jitter at 156.25MHz is 0.494ps (12kHz - 20MHz) and 0.594ps (1kHz - 40MHz).
