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. 48−QFP−1010E FEATURES • • • • • • • Operating voltage range: 2.0V ~ 5.
