      • SI468x DAB_GET_COMPONENT_INFO question

        Thomas Götz | 07/197/2018 | 06:13 AM

        Hello,

        AN649 Rev. 2.0 Table 16. describes the DAB_GET_COMPONENT_INFO response and has an Align Pad after Num μA, while the same AN649 on page 198 has none after RESP26

        the results of CMD 0xBB are these :

        Since both KULTRADIO and ANTENNE BAYERN have Slideshow and Journaline, I assumed i could find here 0x3c and 0x44a as Component Info ? Am I wrong?

      • VCP drivers working for Mac High Sierra 10.13.4?

        Matthew Wilson | 04/109/2018 | 03:30 PM

        I installed this driver on a MacbookPro running High Sierra:

        https://www.silabs.com/documents/public/software/Mac_OSX_VCP_Driver.zip 

        After installing it I'm not seeing a USBTOUART device in my /dev list and I don't see the anything from silabs in SystemInformation.app under USB either.

        Do the drivers work with the latest High Sierra?

      • FM tuning drift any ideas?

        gabriel antonio | 04/108/2018 | 01:50 AM

        Hi,

        This is driving me mad! The set in question is a B&O "mini deluxe" (1963) and in the first ten minutes of use it consistently needs about 500KHz of tuning correction to keep it on tune. After this it's OK for as long as it's on.
        The set is pretty simple and conventional, it uses an ECC85 for the FM front end, followed by an ECH81, EF89, EBF89 and two Ge diodes for the detector. The FM front end is in a metal box and is capacitively tuned.

      • Bad reception of Si4730-D60

        Michael Remennik | 04/98/2018 | 04:30 AM

        We are using Si4730 as a part of out system and are observing a very bad reception. Si4730-D60 is assembled on our PCB designed by us.

        If instead of Si4730-D60 we connect module PL102BA-S V2.0 to power and communication lines of our PCB exactly as Si4730-D60 is connected, the reception is good.

        Can anybody help us solving the problem. We attach the schematic and layout of the area of PCB where Si4730-D60 is assembled.
