2.4 Analog Input and Output Connections

The input signal connections for the PGA854EVM are provided through the use of SMA connectors J3 (IN+), J6 (IN–), and test points TP3 (IN+), TP7 (IN–), located at the left of the EVM. The VOCM input can be provided through screw-terminal connector J1, located on the left of the board, and by default this pin does not need to be driven.

The differential output connections of PGA854 are available through screw-terminal connector J4.4 (OUT–) and J4.1 (OUT+), SMA connectors J2 (OUT–) and J8 (OUT+), and test points TP4 (OUT–) and TP6 (OUT+), located at the right side of the EVM. Figure 2-7 displays a simplified diagram of the PGA854EVM input and output connections.
