Preliminary
EM92602/3A
DUAL PLL FOR 43/46/48/49 MHZ CORDLESS PHONE
4.2.1996
GENERAL DESCRIPTION
The EM92602/3A series are developed for 43/46/48/49 MHz of 25 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. The EM92603A is designed for easy MPU interface. It provides the same
features as the EM92602A , but accepts channel programming via a clocked, serial input instead of parallel BCD
inputs. The EM92602A is selected channels via machanical switches of parallel BCD input.
FEATURES
Include oscillation circuit with external XTAL (10.240 MHz)
Unlock detector
5kHz output for guard tone (EM92603A only)
Standby mode for power saving
2.5 to 5.5V supply range
Base/Handset changeable
Available in 16 pin DIP or SOP
