PLL FREQUENCY SHNTHESIZER FOR PAGER
S5T8808
INTRODUCTION
S5T8808 is a superior low-power-programmable PLL frequency
synthesizer which can be used in a high performance Wide Area
Pager system.
KS8808 consists of 2 kinds of divider block including a 17-bit Shift
register, 16-bit Latch, 14/16-bits Counter, Prescaler, and a phase
detector block including a Phase detector, Lock detector and a
Charge pump.

FEATURES
(Magnification = 1 : 4)
• Maximum operating frequency:
150MHz @ 500mV_P-P, V_DD1 = 0.95V
180MHz @ 500mV_P-P, V_DD1 = 1.0V
• On-chip reference oscillator supports external crystal which oscillates up to 18MHz
• Superior supply current: (V_DD1 = V_DD2 = 1.0V, V_DD3 = 3.0V)
— F_FIN = 90MHz, I_DD1 = 0.6mA (Typ.)
— F_FIN = 150MHz, I_DD1 = 0.9mA (Typ.)
— F_FIN = 180MHz, I_DD3 = 1.1mA (TyP.)
• Operating voltage: V_DD1 = 0.95 ~ 2.0V and V_DD2 = 0.95V ~ 2.0V and V_DD3 = 2.0V ~ 3.3V
• Reference frequency counter divider range: 1 / 28 ~ 1 / 65532 (Multiple 4)
But, the Divider range with FRC_High state: 1 / 7 ~ 1 / 16383
• RX frequency counter divider range: 1 / 28 ~ 1 / 65535
• Package type: 16-SSOP (0.8mm)
