MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145166/D MC145166 Dual PLLs for 46/49 MHz Cordless Telephones MC145167 CMOS These devices are dual phase- locked loop (PLL) frequency synthesizers in- tended for use primarily in 46/49 MHz cordless phones with up to 10 channels. These parts contain two mask- programmable counter ROMs for receive and transmit loops with two independent phase detect circuits. A mon reference oscillator and reference divider are shared by the receive and transmit circuits. Frequency selection is acplished via a 4- bit parallel input for the MC145166. The MC145167 utilizes a serial interface. Other Features include a lock detect circuit for...
