b/w camcorder
i want to build a miniature tv receiver using a camcorder viewfinder and a tv receiver ic. is there any "analog tv receiver ic" ,using which we can tune a signal manually and drive the viewfinder,so that we can see the video in the viewfinder. any ideas? please help.
Is not an easy job:
You can use for TV tuner CXA3235N from Sony,

and for IF and video detector M52342 from Renesas (or Mitsubishi)

Both IC?s are in production.
Just for fun probably much easier is to get a cheap 5? B&W TV with manual tuning (I?ve seen with S50 brand new), and use the internal TV circuit (tuner+IF+detector).

VCRs have tunners that output Video and Audio .Very simple to interface
I started a design several years ago !
There are in the market digital tunners with remote control that sell for S50. nthet have video outpu and audio ,Do a search and you will find them
