| EM92600/1A EM92600/1A DUAL PLL FOR MHZ CORDLESS PHONE DUAL PLL FOR 46/49 46/49 MHZ CORDLESS PHONE GENERAL DESCRIPTION The EM92600/1A series are developed for 46/49 MHz of 10 channels band frequency of cordless telephone which is used in U.S.A.. These devices are dual phase-locked loop frequency synthesizers contained ROM counters for receive and transmit loops with two independent phase detect circuits. A common reference oscillator and reference divider are share 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, 5KHz tone output . The EM92601A is designed for easy MPU interface. It provides the same features as the EM92600A , but accepts channel programming via a clocked, serial input instead of parallel BCD inputs. The EM92600A is selected channels via machanical switches of parallel BCD input. FEATURES * * * * * * * * Include oscillation circuit with external X-TAL (10.240 MHz). Unlock detector. 5KHz output for guard tone. Standby mode for power saving. 2.5 to 5.5V supply range. Baseset/Handset changeable. Available in 16 pin DIP or SOP.
