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 µ-controller (MICOM)
and it also has boost up signal output for fast locking.
16-TSSOP-0044
( Magnification = 1 : 4 )
FEATURES
• Maximum operating frequency: 330MHz @ 300mVP-P, VDD1 = 1.0V, VDD2 = 3.0V
• On-chip reference oscillator supports external crystal which oscillates up to 23MHz
• Superior supply current:
— FFIN = 310MHz, IDD1 = 0.8mA (Typ.) @ VDD1 = 1.0V, VDD2 = 3.0V
• Operating voltage: VDD1 = 0.95 to 1.5V and VDD2 = 2.0 to 3.3V
• Excellent Divider range:
— Ref. Divider:
FRC (0): 1 / 40 to 1 / 65528 (Multiple): Default
FRC (1): 1 / 5 to 1 / 32767
— Rx Divider:
PBC (0): 1 / 1056 ~ 1 / 65535: Default
PBC (1): 1 / 1056 ~ 1 / 262143
• Boost-up signal output for Fast Locking
• In the Standby mode, VDD1 block can be controlled by BSB Pin status
— Standby current consumption: 10µA (Max.)
• Programmable control the output of LD to reduce internal noise
• Programmable 17 / 19-bit shift register value controlled by PBC
• Charge pump output circuitry for passive filter
• Package type: 16−TSSOP (0.65mm)
