  • HU Quality AM/FM RDS/RBDS Radio with Features

    Hi guys

    This is the new thread of the radio project I started about a month ago (link here )

    Before I start going into details I'd like to thank publically Antimatter and Rando for their contribution and support on this project. Their ideas and thoughts made this device mature in design a lot faster and a lot better than what I could do by myself.

    Here we go .
    This device is using 2 ic's made by Philips meant to be used in new generation HU's. The ic's are :

    1) TEA6849H
    New In Car Entertainment car radio
    tuner IC with Precision Adjacent
    Channel Suppression
    (NICE-PACS)

    Webpage/Features/Datasheet here

    2)TEF6890H
    Car radio integrated signal
    processor, mixer and RDS demodulator.

    Webpage/Features/Datasheet here

    First of all I'll give you an idea what you can expect from this device.

    1) Near HU (or equal) reception quality.
    2) 4 channel audio out.
    3) 2 stereo audio inputs, 1 phone mono input and 1 Nav input with beep generator. All with source auto-select and soft-mute.
    4) 1 I2C connector for fast integration with the M10000 motherboard and options to convert to USB or RS232.
    5) 2 I2C connectors available for future expansion (already found compatible DAB modules, still searching for XM modules).
    6) HU style antenna connector for easy installation.
    7) 1 RDS data output header (TTL level signals) with RDS data, RDS clock, RDS quality streams available (will not be utilised in prototypes because we need to focus in reception during initial testing).
    8) Clemens 4 pole power connector (+5v,GND,GND,+12V) so you can use any available power cable from your PSU (this can be changed to a molex connector if required).

    Locating the required ic's has been quite a challenge for two reasons:

    1) Standard promotion politics on behalf of Philips not making widely available parts which are re-branded by other manufacturers/integrators like Alpine.

    2) Small quantities and low prices where always a problem when talking with suppliers.

    That was until I found a company in China (Beijing) who claimed they had the parts available and they were willing to sell in low quantities (10pcs minimum) and their prices are excellent. I thought it was too good to be true until I received the parts.

    The supplier is:

    KaiCongElectronTechCo.,Ltd
    RM510,Zhong Fa Electronic Building,132#
    ZhiChun Rd,Hai Dian District,BeiJing GD100086 China
    Tel : 86-10-82612701
    Fax : 86-10-62635146
    E-mail : [email protected]

    The sales rep I talk to is Chaobo Long ( Andy ).
    I would strongly advice not to contact Andy before we have a working prototype. The reasons are obvious...

    The prices are :

    TEF6890H $8.72/unit for 10pcs quantity
    TEA6849H $6.58/unit for 10pcs quantity

    Time for the pics now
    ( I must apologise in advance for the multiple posts but I don't have a way of hosting those images)

              Our next steps are:

              1) Finalize PCB design and perform "debbuging"
              2) Locate the best priced PCB printer and print some prototype PCB's
              3) Assemble and distribute prototypes to testers/software developers
              4) Testing,Testing,Testing
              5) Final release.

                I've actually done major research into prototyping and creating pcb, and I found the absolute best way is doing it yourself. What you do is get a photolithographic negative of the pcb layout, and a UV light table. Then you get the copper backed boards that are sensitive to UV light. In the end, I got the best boards ever. Extremely professional and small boards. What program are you using for the board layout?

                  So are you going to be selling this as a a final complete hardware product then... Will it ship with assembly required or as a completed plug and play device? Also do you have any US distributors lined up? Also what is the software API interface gonna be like, is it gonna work like a serial device similar to how the USB XM PCR works?

                      We research every possible solution. We use Cadsoft Eagle for the PCB design. I'll look into it but I suspect the best solution in our case is machine fab PCBs. Thanks for the advice .

                        As I said before every relevant info including schematics/PCB layout/source code will be available publically. Fact is that we'll go the SMT route for that device so buying from us or not is based on if you can solder SMT or not. We'll make kits available but with the info provided here you could order the parts and build it yourself...

                        Well we don't consider the commercial side of it yet. It's too early for that. Whatever happens though the fact is that for MP3Car.com members all info will be free...

                        We're free to decide on that one. We make this.... I2C, USB and/or RS232 will be implemented for sure. APIs and SDKs will follow sortly...

                          I can't wait until all the testing is done and the final product is released. I hope it doesn't take too long. And thanks for making a new thread the other one was getting way too big to keep up with.

                            seth, i hate to bust your chops already but when do you see this unit at the "final release" stage

                            I ask cause i basically have all my carPC parts, my delay is waiting for good HU replacement. I was going to set it up next week, but with XM and wait....but now XM is gone too and i need some kind of radio
                            just want to get an idea on how much longer I have to wait to setup my carPC

                            thanks

                              I have a question on the 4 channel audio out. Will this output be strong enough that I will not need a line driver for my amps? I know the sound card outputs are not stronge enough and there are problems with sound quality.
                              Also will I be able to put the output from my sound card into this unit and then send it to the amp? Let me know if this is how it can be used or if I am getting it wrong.
