EM92600/1C
DUAL PLL FOR 45/48 MHZ CORDLESS PHONE
4.23.1995
GENERAL DESCRIPTION
The EM92600/1C series are developed for 45/48 MHz of 10 channels band frequency of cordless telephone
which is used in Mainland China. 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 EM92601C is designed for easy MPU interface. It
provides the same features as the EM92600C , but accepts channel programming via a clocked, serial input
instead of parallel BCD inputs. The EM92600C 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.
