The ADL5201 datasheet provides the input informationhowever I didn't see any information regard Voh / Volor Ioh / Iol for SDIO.
I don't see a separate supply for SPI though the datasheetlists 3.6v as the maximum input rating for A0 - A5 ...what's the voltages (and available currents) when readingback from the device?
I did see the previous post asking about the SDIO high level... I'm looking for additional information (i.e. the currents).Specifically wanted to confirm there is 2 mA of drive available.
Could you share your SPI clock rate ? The capacitive loading on SDO can become a problem, depending on clock frequency and amount of cap.
I have flexibility regarding the SPI clock rate ... for the sake of discussion let's say 8 MHz.
I'm adapting the ADL5201 3-wire SPI interface to 4-wires using a couple of buffers. Thequestion is does the ADL5201 have enough drive to handle the 1.2k resistors when outputing alow (circuit attached)?
Sorry for the delay, but I've been discussing with our design team. Their estimates are 10 mA sink/source.
No problem ... I appreciate the info and the effort checking with them.
