PLL Frequency Synthesizer for Pager
TEL-98-D001-R1
Jan 1998
Preliminary
KS8808A is a superior low-power-programmable
PLL frequency synthesizer which can be used in a
high performance Wide Area Pager system.
KS8808A consists of 2 kinds of divider block including
a 17bit Shift register, 16-bit Latch, 14/16-bit Counter,
Prescaler, and a phase detector block including a
Phase detector, Lock detector and a Charge pump.
