ENHANCED-1 CHIP CT0 RF IC

INTRODUCTION

S1T8528 is a 1 CHIP RF IC which can be used in high performance

CTO CLP systems at max. 60MHz. S1T8528 is designed to include a

receiver, PLL and COMPANDER to minimize PCB space

requirements. Improved RX characteristics such as inter-modulation,

spurious response and adjacent channel interface have been

included to satisfy the universal standards.

The 1 CHIP RF IC has considerably reduced the cost by including a

build-in 1’st mixer, low battery detector, fMCU, RSSI, RF regulator

and speaker amp. Also, it fulfills carrier detector threshold control,

speaker volume control, operating mode selection and MUTE function

using S/W, thus making external application easier.
