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.
