FLEXchip SYSTEM DESIGN
The FLEXchip IC connects to a receiver capable of converting a 4-level audio signal into a 2-
bit digital signal (see
Figure 2
). The FLEXchip IC has eight receiver control lines used for
warming up and shutting down a receiver in stages. The FLEXchip IC has dual bandwidth
control signals for two post-detection filter bandwidths for receiving the two symbol rates of
the FLEX signal. The FLEXchip IC has the ability to detect a low battery signal during the
receiver control sequences. It interfaces to a back-end host MCU through a standard SPI. It
has a 38.4 kHz clock output capable of driving other devices. It has a 1 minute timer that
offers low power support for time of day function on the host.
All data communicated between the FLEXchip IC and the host MCU is transmitted on the
SPI in 32-bit packets. Each packet consists of an 8-bit ID followed by 24 bits of information.
The FLEXchip IC uses the SPI bus in Full Duplex mode. In other words, whenever a packet
communication occurs, the data in both directions is valid packet data.
