I've finished a layout for the PRS10 interface board.
The board has a few features not on the SRS PRBB breakout board:
1) PPS output is buffered by an ACMOS gate. The PRS10 PPS output is very weak.
2) Added a sine wave squarer for generating an ACMOS level square wave output.
3) Added a pin header jumper block for configuring the board for the PRS10 configuration. The PRS10 has four dual-function pins. The function of the pins is determined by resistors inside the PRS10. The SRS PRBB board uses some (undocumented) solder jumpers.
