Rf Single Chip For Cordless Phone

The HT9015 is an RF single chip for cordless phone systems. Internally these are three major parts, a PLL an IF decoder and a compander. The PLL provides Radio channel selection for either the transmitter or receiver. Frequency locking status of the selected channel CAN be monitored by a control Register The IF decoder provides two frequency down converters that let high frequency signals pass through a mixer and local Oscillator to be low- ered for frequency even base band signals. It also provides an RSSI (receiver signal strength indicator) function to detect the IF output sig- nal strength and built-in noise detector for S/N quality. The compander provides better S/N ratio for Audio signal processing. The HT9015 has a wide-range applications in FM/FSK, Transmitting/Receiving of VHF bandwidth including cordless phone, narrow band voice and data transceiver systems. The most significant advantage of the HT9015 is in the reduction of many external compo- nents making it well suited for cordless phone baseset, handset Radio section. By Holtek Semiconductor Inc.
