Thread starter #1
Hello Everyone . Well After Building a Audio Transmitter Now i want to transmit Video Signals as well I have found This great IC . it is a VHF Audio/Video Modulator with RF Output level of 80dbuV . and i think if i connect a input of a camera and then connect an antenna at this IC's RF Out Pin and Tune into my TV i would have a Video Transmitter. The IC is from freescale semiconductor( previously Motorola semiconductor) . The IC is MC44BC375 . it is available at digi-key. The datasheet is attached . and please do comment to this topic . Thank you bye.

Be careful with the PCB layout!

The IC is for the American NTSC TV system. Where are you going to find an American TV in your country? Make one?

well i have reconsidered the IC . Freescale also have a really nice IC . which is truly compatible . it is MC44BS373CA . here is the link http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MC44BS373CA#orderables

It has frequency selection with 250Khz steps for VHF to UHF and has a slightly higher RF Ouput Level . 82dbuV .

The only problem with is the I2C Bus :mad:
How in the world i am going to program it using the I2C Bus . It is really complicated . I have to study a lot about I2c . But for now i am preparing for the exams.

We don't mind helping you but we won't do all of the work for you. Please post what you've already done including any ideas you've had and we might be able to make some suggestions. If you've got completely no idea then may be it's your lecuturer's fault and it isn't right that you make him/her look good by cheating and copying from the Internet.

what type of antenna???

hi everyone.. i know its been almost a year since this topic was written.. and since im new i cant post a new topic all i can do is post replies.. anywayz..FAIZAINBROHI.. um.. i read what u posted.. and i looked around.. since my project is a camera that transmitts video on the rf.. so i looked around.. and checked out a lot of freescale/motorolla ICs.. and this was the most appropriate one for our project.. i read the pdf in detail..and it didnt have any information about the type of antenna that should be used.. i know that the power of the signal will determine the range of the transmission and that the antenna should be matched to the impedence of the IC.. but what type of antenna should be used?? can anyone help me??
