May 31, 2007 RE: ATCB004933 for Delphi Automotive Systems FCC ID: L2C0035TR & IC: 3432A-0035TR The following is in response to the comments made on the above referenced application. 1. This Part 15 transmitter application contains conflicting information on the operating frequency. The test report in Section 3.1 says it operates at 125 kHz. In the application it’s listed as operating at 126.2 kHz because that’s where it was measured in the test report. Finally, the operational description says it operates at 131 kHz. Please clarify and correct the incorrect information as necessary. The Test Report and Operational Description have been corrected to reflect the measured operating frequency of the device. The Operational Description provided was from a much earlier version of the device and had not been updated for the change in frequency. 2. The schematic diagram shows connections for two coils or antennas. Please describe if one is for receiving signals and the other is used for transmitting signals or if both can be used for transmitting signals. If both can transmit signals, please confirm that they both were evaluated for radiated emissions testing. The ports shown in the schematic refer to H-bridge differential leads of a single LF coil. No secondary coil exists.

PRODUCT OVERVIEW The Passkey III Reader/Exciter module is part of a vehicle immobilization system intended to prevent amateur theft. The module, through its coil antenna, energizes a transponder embedded in the head of the ignition key and reads the unique security code from the transponder. The module sends the security code it receives from the transponder to a Controller Module for authentication. The Passkey III Reader/Exciter module consists of the following functional block: 1. Closed-Loop Drive/Oscillator 2. Resonant L-C 3. Coil Drive Wave Shaping 4. AM detector 5. Data Filtering/Amplification The Reader/Exciter (R/E) module receives power from the vehicle body controller module when vehicle ignition switch is activated. Once power is delivered to the R/E module, a current-controlled oscillator is activated with nominal frequency set to 125 kHz. The square wave signal generated by the oscillator is fed to a wave shaping stage and drives a series resonant RLC nominally tuned to 125 kHz (with lock cylinder effect). The inductor or the coil antenna is a 97-turn, 33 gauge wire wound with inside diameter of approximately 34.38mm. The coil antenna is fitted and positioned around the vehicle ignition lock cylinder. The signal of the oscillator driving the series RLC is fed into a phase detector along with the sinusoidal resonant voltage formed by series RLC. The difference of phase between the oscillators drive signal and the sinusoidal resonant signal is converted into current sink or source to the current controlled oscillator. It effectively forms a closed loop system whereby the oscillator frequency tracks the resonant frequency of the series RLC. The current generated in the coil antenna produces a magnetic field around the coil, which extends to couple to a transponder in the key. The coupled energy from the R/E module energizes the transponder and in turn transponder modulates the magnetic field in accordance to the security code at a rate of 2 kHz.
