📥 Download Datasheet

General Description

Pin No 1 2 3 4 Symbol OSCI OSCO VDD3 PDA I/O I O

O Description These input / output pins generate the reference frequency.

In case of an OSCI pin, external reference frequency can be input through an AC coupling.

Overview

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.
