2.1.8 High-Frequency Input and Output

The TPLD2001 can support up to 25MHz, but for frequencies that high, the parasitics on long, non-impedance matched traces can disrupt the signal. The TPLD2001 EVM has a pair of SMB connectors for high frequency input and outputs.

To use the high-frequency input, first, disconnect R14. This will disconect the high-frequency input trace from the rest of the board, decreasing parasitics. Then, solder 200 Ohm resistors in soldering points R47, R48, R49, and R15. This is equivalent to a 50 Ohm pull down resistor on the line for impedance matching. The high-frequency input has a limit of 25MHz and connects to IO17.

To use the high-frequency output, ensure a 50Ω resistor is soldered to R50 for impedance matching. The high-frequency output is output from IO15 and has a limit of 12.5MHz.
