PIYH3623-05A4T1:10 Drifting Vehicle Nissan Silvia S15

MATTEL: G3451 49MHZ TX 49.860MHZ Transmitter Operational Description The 1:10 Driftinf R/C radio control transmitter is a low powered, hand held V.R for controlling the movement of a toy car
the transmitter is powered by a 6.0V battery(4XAA) ,it is designed to operate on a single fixed frequency in the 49.860MHZ band .please see the attached block diagram and schematic. Transmitter is being used a proportional Remote Control BDEM78458 integrated circuit, the BDEM78458 is able to Dual pulse width modulation with 10-bit resolution with programmable pull-high I/O pins. When set any where of the V.R, it will have digital control signals, via built-in crystal oscillator and power amplifier, circuit comprised of a crystal X1. The RF carrier signal is modulated by digital control signal. The modulated output of pin56 is capacitably coupled via R10, C16, R7 to the antenna through a pi matching network comprised of C13 C14 and L5. T1 is adjustable. All tuning and verifications are performed by the manufacturer and there are no adjustments that can be made by the User. No external ground is required or used with this transmitter

The EUT is powered by 4 x 1.5V “AA” size battery. There are two control stick and a on / off switch in the EUT. When switch “on” the unit and push the forward or backward control stick once, it will transmit a radio signal for receiver go forward or backward. When the turn left or turn right wheel trigger once, it will transmit a radio signal for receiver turn left or turn right. The brief circuit description is listed as follows: - U2 and associated circuit act as encoder. - X1, Q2 and associated circuit act as oscillator. - Q3 and associated circuit act as amplify. - Q1 and associated circuit act as voltage readjust. 1.2 Related Submittal Grants This is a single application for certification of a transmitter. The receiver for this transmitter is authorized by Certification procedure. Page 3 of 1…
