GENERAL DESCRIPTION
The EM92600/1A series are developed for 46/49 MHz of 10 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, 5KHz tone output . The EM92601A is designed for easy MPU interface. It
provides the same features as the EM92600A , but accepts channel programming via a clocked, serial input
instead of parallel BCD inputs. The EM92600A 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.
• SERIES
