Description

The NXP PCF7938, an immobilizer transponder for advanced security, builds on the success of the field-proven PCF7936 /37 and PCF7939 (AES-128-Bit). It offers advanced security with a. 96-bit secret key, enabling an easy migration path for customers using the PCF7936 . It offers more memory to store user data,. variations. Security transponder operation is compatible with the PCF7936 /37 & PCF7938 families, for simple system upgrades. The transponder requires no battery supply, so full operation is guaranteed, even when the battery is low. A complete suite of on-chip memory is available. For customer application software, up to May 21, 2015 2.2 Protocol. Modulation read/write device transponder: 100 % ASK and binary pulse length coding. Modulation transponder read/write device: Strong ASK modulation with anti-collision, Manchester and Biphase coding. Fast anti-collision protocol. Cyclic Redundancy Check (CRC). Summary. In this application note you can find an application description of the triple video output amplifiers with the type numbers TDA6107JF, TDA6107AJF, TDA6108JF and TDA6108AJF. All types include three video output amplifiers in a DBS9MPF package, version SOT111-1. The types are all functional the same, but
