ENHANCED-1 CHIP CT0 RF IC
S1T8528
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.
