EM4100
Memory Array for Manchester & Bi-Phase encoding ICs
The EM4100 contains 64 bits divided in five groups of
information. 9 bits are used for the header, 10 row parity
bits (P0-P9), 4 column parity bits (PC0-PC3), 40 data bits
(D00-D93), and 1 stop bit set to logic 0.

4 column parity bits
The header is composed of the 9 first bits which are all
mask programmed to "1".
Due to the data and parity
organisation, this sequence cannot be reproduced in the
data string. The header is followed by 10 groups of 4 data
bits allowing 100 billion combinations and 1 even row parity
bit. Then, the last group consists of 4 event column parity
bits without row parity bit. S0 is a stop bit which is written to
"0"
Bits D00 to D03 and bits D10 to D13 are customer specific
identification.
These 64 bits are outputted serially in order to control the
modulator. When the 64 bits data string is outputted, the
output sequence is repeated continuously until power goes
off.
Memory Array for PSK encoding ICs
The PSK coded IC's are programmed with odd parity for P0
and P1 and always with a logic zero.
The parity bits from P2 to P9 are even.
The column parity PC0 to PC3 are calculated including the
version bits and are even parity bits.
Code Description
Manchester
There is always a transition from ON to OFF or from OFF
to ON in the middle of bit period. At the transition from
logic bit “1” to logic bit “0” or logic bit “0” to logic bit “1” the
phase change. Value high of data stream presented below
modulator
switch
OFF,
low
represents
switch
ON
(see Fig. 6).
Biphase Code
At the beginning of each bit, a transition will occur. A logic
bit “1” will keep its state for the whole bit duration and a
logic bit “0” will show a transition in the middle of the bit
duration (see Fig. 7).
PSK Code
Modulation switch goes ON and OFF alternately every
period of carrier frequency. When a phase shift occurs, a
logical "0" is read from the memory. If no shift phase
occurs after a data rate cycle, a logical "1" is read
(see Fig. 8).
