2.2.1
This circuit generates a clock pulse (CLK). The clock
pulse is generated by an on-board time base oscillator.
The clock pulse is used for baud rate timing, data
modulation rate, etc.
2.2.2
This logic acts upon the serial data (154 bits) being
read from the memory array. The data is then encoded
into Manchester format. The encoded data is then fed
to the modulation transistor in the analog front-end
section. The Manchester code waveform is shown in
Figure 2-2.
