RC filter on TDA1543 inputs

[ash_dac]

Hi,

Noticed on most of my commercial cdp's / dacs (tda1541a, tda1545a) there are input resistors on the I2S pins. Also I have an article that mentions using 3 20ohm resistors on the I2S inputs on tda1545. The links listed below also mention the use of a capacitor to form a RC filter on the I2S inputs.

Has anyone tried adding a RC filter on each of the TDA1543 inputs?

+ any recommendations for introductory electronics text ?

I'm thinking of ordering "The Art of Electronics" (Paul Horowitz and Winfield Hill) because at the moment i'm having to learn stuff adhoc (using google) when reading articles / posts because I have no foundation in electronics.




Kind regards,


Ashley

It is quite a leap from AOE to High Speed Digital Design. High Speed Digital Design is anything but an introductory text and is highly specialised. Want to know how to build a barrel shifter or a clock divider? Look elsewhere. Want to make said barrel shifter or clock divider run at 500Mhz? High Speed Digital Design is the book for you. AOE is much more general and would be an ideal introductory text.

Johnson's book is not for the noob..........plus, it isn't cheap. Geared towards people who do high speed stuff all day long, so they can justify the cost.

Got my copy used off amazon.com for $50.

It's not for the 'noob' who doesn't know how electric/magnetic fields interact or how transmission lines interact, but once you get that part down then the book makes lots of sense. Everything is highly explained, and there's very little actual math in the book.
