S1T8528 - ENHANCED-1 CHIP CT0 RF IC

Pin No 1 Symbol PDT Description Phase detector output terminal of the transmitter at PLL. If fTX > fREF or fTX is leading → the output is negative pulse If fTX < fREF or fTX is lagging → the output is positive pulse If fTX = fREF and the same phase → the output is High Impedance Compressor output te.

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 de.
