The appnote https://www.ti.com/lit/an/scea065b/scea065b.pdf, "Low Voltage Translation For SPI, UART, RGMII, JTAG Interfaces" has a section about RGMII. In section 2.5.3 it describes the low intersignal skew of a 74AVX8T245 part, including values and scope traces to show. Is the same information available for the SN74AVC16T245 part. This device covers the two voltages I need to translate between, and offers a 30% more economical solution. I'd like to know if it's inter-signal skew is of similar magnitude if I keep the signals grouped within an 8 bit section.
