Advance Information

P SUFFIX

PLASTIC DIP

CASE 648

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.
