PLL FREQUENCY SYNTHESIZER FOR PAGER
S5T8809
INTRODUCTION
S5T8809 is a superior low-power-programmable PLL frequency
synthesizer which can be used in high performance / Simple
application for a Wide Area Pager system.
S5T8809 consists of 2 kinds of divider block including a 19-bit Shift
register, 16/18-bit Latch, 13/15bits R-counter and 16/18-bit N-
Counter, 32/33 Prescaler, and a phase detector block including a
Phase detector, Lock detector and a Charge pump.
S5T8809 also has a battery saving mode which can control each
register block by serial control data from the
碌-controller
(MICOM)
and it also has boost up signal output for fast locking.
