8N4S271 - Block Diagram
Description
The 8N4S271 is a factory frequency-programmable crystal oscillator with very flexible frequency programming capabilities. The device uses Renesas' fourth generation FemtoClock® NG technology for an optimum high clock frequency and low phase noise performance. The device accepts 2.5V or 3.3V supply and is packaged in a small, lead-free (RoHS 6) 6-lead ceramic 5mm x 7mm x 1.55mm package.
The 8N4S271 can be factory programmed in the range from 15.476MHz to 866.67MHz and from 975MHz to 1,300MHz and supports a very high degree of frequency precision of 218Hz or better. The extended temperature range supports wireless infrastructure, telecommunication, and networking end equipment requirements.
