DATA SHEET  
3.6.1. Specification of Biphase-M Output  
Definition of Biphase-M Pulses  
In case of output format Biphase-M, a continuous data  
stream is provided. It consists of:  
A logical “0” is coded as no output level change within  
the bit time. A logical “1” is coded as an output level  
change between 50% and 80% of the bit time. After  
each bit, an output level change occurs.  
– 1 SYNC bit defining the bit time tp0,  
– 14 data bits (DAT)  
– 1 parity bit (DP)  
Data Bits (DAT)  
– a gap (signal quiescent) of 8 x tp0  
The 12 MSB of the 14 data bits (DAT) contain the digi-  
tal output reading.  
The complete signal period is T = 24 x tp0.  
The signal quiescent level and the polarity of the  
SYNC bit is shown in Fig. 3–9.  
Data Parity Bit (DP)  
This parity bit is “1” if the number of zeros within the 14  
data bits is even. The parity bit is “0” if the number of  
zeros is odd.

SYNC Bit Polarity

positive  
Note: If the part number output is activated, the part  
number will be transmitted 2 times after  
power-up (see Fig. 4–5 on page 33). The first  
Biphase-M protocol, respectively, the first PWM  
period after power-up, is not valid.
