MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145168/D MC145168 Advance Information Dual PLLs for 46/49 MHz Cordless Telephones MC145169 CMOS These devices are dual phase–locked loop frequency synthesizers intended for use primarily in 46/49 MHz cordless phones with up to 15 channels. These parts contain two mask–programmable counter ROMs for receive and transmit loops with two independent phase detect circuits. A common reference oscillator and reference divider are shared by the receive and transmit circuits. Other features include a lock detect circuit for the transmit loop, illegal code default, a buffered oscillator output for mixing purposes in the system, and a 5.0 kHz tone output.
