Instrumentation amplifier datasheets typically show a graph (or several variations) of the Output Swing vs Input Common-Mode Voltage, also known as the Diamond Plot, which is a comprehensive graph of all external and internal headroom limits. Given enough basic information about a circuit, the Diamond Plot can be adjusted for various Supply Voltages, Gains, and Reference Pin Voltages.

JESD204 Receiver Transport Layer Design File Package

This command line executable tool generates a Verilog module which implements the JESD204 receive transport layer. The user specifies in a configuration file one or more modes to be supported by the transport layer module. These modes are defined as a set of JESD204 parameter values: L, M, F, S, N', and CF. The transport layer converts JESD204 lane data output from a JESD204 link layer IP to a data bus with a fixed width, containing interleaved virtual converter samples. Both JESD204B and JESD204C link layers are supported.
