2. SYSTEM DESCRIPTION
This Standalone (SRx) receiver has to support the receipt of RF telegram from transmitted in free air way by
corresponding transmitter and to transmit them to a host module (e.g. the Body Control Module and PIC
module).
module).
Ø KOR-baby board receiver 315, FSK -1K data rate based on Infineon TDA 521x , which module
optimized maximum for the enhanced RF working range with LNA and data filter characterization.
All receipts of RF telegram has to be transmitted to a host module with the serial linked communication line
which line of single-wired serial link must be available to communicate with bi-directional for a bit rate 2.4k
bauds for BCM for a bit rate 9.6k bauds for PIC.
which line of single-wired serial link must be available to communicate with bi-directional for a bit rate 2.4k
bauds for BCM for a bit rate 9.6k bauds for PIC.
This SRx provide a variant 4 resistors with pull- Ground down for reading of mounted code.
The processor of the SRx was selected as 8-bit Single-chip NEC’s Micro-controller with 78KO series
The main function of generic SRx is
Ø RF signal detection (in-band)
Ø Data signal demodulation.
Ø Manchester and Shark protocol detection
Ø Self-polling for the standby current consumption
Ø Wake up function for the host module
Ø 315MHz RF data reception
Ø Serial communication with the single –wired link com.
