    Marantz 74CD80/04B Optical port required

    Hi all, this is an unusual one, as it has four pins instead of the three, I'm used to seeing.

    Port is manufactured by Toshiba & can't seem to locate one.

    Couldn't find an exact datasheet for it but the one for TOTX173 looks like a match, as I have proved pin 1 GND & pin 3 VCC are same.

    Can anyone help?

    It's from a Marantz 74CD80/04B

    See pictures for details.

    The totx172 and totx173 seem to be the same, the (8.2k) resistor is current limiting for the L.E.D. the txt177 is the newer 3 pin version, it functions the same but does not require the external resistor. (but the pins would obviously not line up with the 4 pin version)

      I couldn't find a decent datasheet for the TOTX172. It's used in a few other CD players.
      TOTX17_ is 5V, TOTX14_ is 3.3V power.
      TOTX173 is a 5V part, 6MB/sec. so it can't do 192kHz. The only risk is the speed rating. I would say it would work fine.

        Thanks very much Redwire

        The 173 differs, as it seems to be an upright type,but as a last resort will have to make it fit.

          please help, friend, thinkpad L480 NM-B461 rev 1.0 JDOCK1 type C port 5volt only, thank you
          by fredyjbi
          I have a thinkpad L480 NM-B461 rev 1.0 laptop functioning normally with Type 1 port (JUSBC1)
          if you use port type C 2 (JDOCK1) with a usb type meter it only displays 5v, thank you
          I tried to look at the schematic diagram USBC_VBUS20, which is the port path from JusBC 1 to U4701 then goes to the system2 charging IC, why is there no system2 path leading to the charging IC on the TYPEC_VBUS20 port which is JDOCK1, thank you for your help.

          if you look at the power sequence there must be 2 types of port type C a (JUSBC1) via U4701 and port type C b (JDOCK1)
          On the type...
