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 NCounter, 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 m-controller (MICOM) and it also has boost up signal output for fast locking.
