6. The control signals from the Driver Module is decoded and the following signals are
generated.
• RF Router Control Signals (To RF Router Block)
• RRx Reset Signal (To RRx)
• External MUX Control Signals (To Coil Ports) : The CPLD just pass though this signal to each
Coil Port.
• Body Select Signal (To RF Router Block)
• Loopback Select Signal (To RF Router Block)
The control signals from the RRx Module is decoded and the following signal is generated.
• R1 Control Signals (To each Mixer Module)
• RCVR_UNBLANK
The CPLD provides the control signals to switch the receive path to loopback circuitry
when the UNBLANK signal is Logic Low (Blank state).
7. SRI3 interface consists of the following signals.
• COIL ID and HART
• COIL Present
• Body Transmit ENBL
• COIL LED
