MC145167

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145166/D Dual PLLs for 46/49 MHz Cordless Telephones 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 common reference oscillator and reference divider are shared by the receive and transmit circuits. Frequency selection is accomplished via a 4–bit parallel input for the MC145166. The MC145167 utilizes a serial interface. Other features include a lock detect circuit for the transmit loop, illegal code default, and a 5 kHz tone output. Synthesizes Up to Ten Channel Pairs Maximum Operating Frequency: 60 MHz @ Vin = 200 mV p–p Operating Temperature Range: – 40 to + 75°C Operating Voltage Range: 2.5 to 5.5 V On–Chip Oscillator Circuit Supports External Cry...
