You are the new chief PCB designer for a small company who are about to become heavily involved in the design and realisation of digital timing products. Your management wants to prove the path from design entry to final design data production. Consequently, your first task within the company is to take a design from concept through to completion. Given the nature of the company business, it has been decided the test design will be a digital clock, the block diagram of which is illustrated below. An additional requirement is miniaturisation and the board size should be as small as is practically possible.
Each of the elements can be realised from 7400-series TTL in SMD packages. The circuit below shows the internal components and connections for the divide-by-60 block above. The counters are 74160 and the 7-segment BCD is a 7447. Any additional information is readily available in data books and the internet.
