The PT8A995 and PT8A996x provide a simple and economic solution for basic Digital Proportional R/C car toys. The chipset uses CMOS LSI Analog and Mixed Signal technology. They provide high quality encoder/decoder circuit. PT8A995 severs as an encoder. To obtain accurate timing easily, Manchester encoding is employed. Some digital modulation scheme can be used, e.g., general ASK, OOK, FSK and QPSK. OOK is easy to implement and low cost. The PT8A996x provides a simple and cost effective solution for basic Digital Proportional R/C car toys with PT8A995 together. RF circuit in receiver side can demodulate RF signal. The demodulated signal will be amplified and filtered. After that, the base-band signal is formed. DPLL is adopted to...
