Typical Performance Characteristics
Functional Description
The simplified block diagram below shows the 22-bit data register, two 15-bit R Counters and the 15- and 18-bit N Counters
(intermediate latches are not shown). The data stream is clocked (on the rising edge of Clock) into the DATA register, MSB first.
The data stored in the shift register is loaded into one of 4 appropriate latches on the rising edge of LE. The last two bits are the
Control Bits. The DATA is transferred into the counters as follows:
