TD7101F-the integrated circuit of programmable preset frequency splitting

Published:2011/6/4 7:36:00 Author:qqtang | Keyword: frequency splitting, integrated circuit | From:SeekIC

TD7101F is a preset frequency splitter in the digital modulation system of low-voltage power supply, whose maximum working power is 250MHZ.1. Function features TD7101F includes the frequency splitting circuit, the frequency splitting preset circuit and other additional function circuit. As the frequency of FM signal is 108MHz, and it is added with a middle frequency of 10.8MHz, so the maximum frequency of FM is 118.7MHz, usually, such a high frequency can not work in CMOS/PMOS. The function of TD7101F is to split the frequency, so that it will be lower than the working frequency of the integrated circuit.
