Re: PGA
programmable gain amplifiers are devices which help to control gain of analog or digital signals through serial or parallel digital i/ps each digital i/p controlling the gain have certain gain factor if there is a 3-bit gain control port you can have 8 different steps of gains. u just...

PIC17C44 Assembely.
i m making amanual router where one will be able to route voice data by chossing the destination
at the moment using his pc.For switching we'll be using AD75019 which will serially cascaded.
what we will be doing is sending routing information to our PIC17C44 which be...
i m making a manual router where voice data will be switched using AD75019 crosspoint switch ic. i will be controlling the cascaded AD75019s with the help of PIC17C44/jw. What i intend to do is creat a table where the status of 256 switches of each AD75019 will be polled and serially transfered...
