other for steering
• 32 steps for each of two analog channels
• Fine tuning selection for two analog channels
• Few external components needed
• Closed loop adjustment for servo motor (996x)
• Built-in voltage regulator (996x)
• Package: 16-pin DIP (995P), 20-pin DIP (996xP),
20-pin SOIC (996xS), see Ordering Information.

The PT8A995 and PT8A996x provide a simple and eco-
nomic 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 tim-
ing easily, Manchester encoding is employed. Some digi-
tal 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 so-
lution for basic Digital Proportional R/C car toys with
PT8A995 together. RF circuit in receiver side can de-
modulate RF signal. The demodulated signal will be am-
plified 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 mo-
tor 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 dif-
ferent capability Servo.
