Page 12: Power Supplies
The evaluation module includes a DB-25 connector, labeled J5, which is used to interface the PGA4311-EVM with a PC parallel (printer) port. The evaluation module software utilizes the parallel port to communicate with the PGA4311’s serial interface. An interface cable is supplied as part of the evaluation module package. -
Page 13: Registor Loop-Back Jumper
The serial interface is basically a 32 bit serial IN, serial OUT shift register. The SDI pin is the input, while SDO is the output. As 32 bits of new data are shifted into the PGA4311, the previously programmed 32-bits are being shifted out. This allows the user to read back the values to determine if the device is being programmed correctly. -
