PLL FREQUENCY SHNTHESIZER FOR PAGER
S5T8808A
INTRODUCTION
S5T8808A is a superior low-power-programmable PLL frequency
synthesizer which can be used in a high performance Wide Area
Pager system.
S5T8808A consists of 2 kinds of divider block including a 17bit 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.
16−TSSOP−0044
FEATURES
( Magnification = 1 : 4 )
• Maximum operating frequency:
120MHz @ 500mVP-P, VDD1 = 0.95V, VDD2 = 3.0V
165MHz @ 500mVP-P, VDD1 = 1.0V, VDD2 = 3.0V
• On-chip reference oscillator supports external crystal which oscillates up to 18MHz
• Superior supply current:
FFIN = 90MHz, IDD1 = 0.6mA (Typ.) @ VDD1 = 1.0V, VDD2 = 3.0V
FFIN = 150MHz, IDD1 = 0.9mA (Typ.) @ VDD1 = 1.0V, VDD2 = 3.0V
• Operating voltage: VDD1 = 0.95 ~ 2.0V and VDD2 = 2.0 ~ 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−TSSOP (0.65mm)
