General Description

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 generate

sampling clock. An internal A/D converter is required

to make servo motor work well. The inputs are SRV

and OFFSET. Over-load protection mechanism is

built-in to meet Toy Safety Requirement.

The PT8A996x provide four solutions for toy car by

different capability Servo.
