CD2003 Radio Chip


The Alba CCP1 utilises the CD2003GP radio integrated circuit (IC) which minimises the component count drastically. If you are into building radios, then this might be the IC to play with. Apart from the tuning coils and ferrite rod, the component count is very small with just a handful of ceramic disc capacitors. There is a generous drizzling of wax everywhere so that the components do not move.




The CD2003GP is an excellent single chip AM/FM radio solution requiring very few external components. The IC has all the blocks required for building a stereo receiver, and it is amazing to think that they can pack the oscillator, mixer, and multiplex all in this one IC. This IC has very good reception, and is worth playing with.

Circuit Diagram

This is the basic test circuit for a typical AM/FM radio receiver. Selection is solely dependent upon the oscillator and resonator components.

Even a budget-end product such as this is worth collecting.

Ferrite Rod

Ferrite Rod

This shows the ferrite rod with the antenna coils. The tuning dial needle mechanism consists of a plastic gear mechanism. There is also a very low profile variable tuning capacitor below the ferrite rod.
