HARDWARE DESCRIPTION  
The 71M6103/71M6113/71M6201/71M6203/71M6601/71M6603 (71M6xxx) remote sensor ICs integrate  
all functional blocks required to implement an isolated front-end with digital communication capability.  
Figure 1 shows the 71M6xxx IC block diagram. The chip includes the following:  
Preamplifier with a fixed gain  
22-bit delta-sigma ADC  
ADC voltage reference  
Temperature sensor  
VCC monitor  
Power-on reset circuitry  
Bidirectional pulse interface  
Active rectifiers for supply-voltage generation from the power pulses provided by the 71M654x  
Digital control section providing control registers for the selection of operation modes

FUNCTIONAL DESCRIPTION  
During normal operation, the SP and SN pins of the 71M6xxx are connected to the pulse transformer.  
When PLL_FAST = 1 in the 71M654x, power pulses generated by the 71M654x arrive every 610.35ns.  
The PLL in the 71M6xxx locks to these incoming power pulses. The communication between the  
71M654x and the 71M6xxx is synchronized to the multiplexer frames of the 71M654x. The  
communication protocol is Maxim Integrated-proprietary, and details are not described in this data sheet.  
All aspects of the communication between the 71M654x and the 71M6xxx are managed on the hardware  
level and they are completely transparent to the user.  
The communication interface can run at two different data rates. Power pulses are generated every  
610.35ns if the PLL_FAST register in the 71M654x is set to 1, and every 1.905µs if PLL_FAST is set to 0.  
The power pulses are 101.7ns wide with PLL_FAST = 1, and 160ns wide with PLL_FAST = 0.
