... A[0:4] Figure 30. Control Interface (Simplified Schematic) AD8150 CONTROL INTERFACE The AD8150 control interface receives and stores the desired connection matrix for the 33 input and 17 output signal pairs. The interface consists of 17 rows of double-rank 7-bit latches, one row for each output. The 7-bit data word stored in each of these latches indicates to which (if any) of the 33 inputs the output will be connected ...

... CC EE levels when operated from a –5 V supply (V –5 V). To save power, the AD8150 can run from a 3.3 V supply to interface with low-voltage PECL circuits or a –3.3 V supply to interface with low-voltage ECL circuits. The AD8150 utilizes differential current mode outputs with individual disable control, which facilitates busing together the outputs of multiple AD8150s to assemble larger switch arrays ...

... Power Supplies There are several options for the power supply voltages for the AD8150, as there are two separate sections of the chip that require power supplies. These are the control logic and the high-speed data paths. Depending on the system architecture, the voltage levels of these supplies can vary ...

... This will show a full array of “buttons” that allows the connection of any input to output of the AD8150. All of the outputs should be in the output “OFF” state right after the program starts running. Any of the active buttons can be selected with a mouse click which will send out one burst of programming data. After this, the PC keyboard’ ...
