Introduction
The compact-disc player market is now
mature, in fact saturated, in the home audio
and portable fields. However, this is not the
case in the automobile field, where the
market is expected to grow at a rate of about
10% annually. The most recent player
systems are required to offer high cost
performance as well as be space saving by
reducing the number of components.
Especially in the field of automobiles, a
compact disc player needs to be as small as
possible because it must coexist with other
equipment such as a mini-disc player and an
in-dash TV in a limited space. The single-
chip LSI for CD, µPD63710, to be
introduced in this article has been developed
to satisfy these requirements.
The µPD63710 integrates the functions
necessary for a compact disc player on a
single chip, and in addition to existing-
product specifications, contains an RF
amplifier and its peripheral components to
enhance system integration. As a result, this
LSI can reduce the number of external
components, helping to create a small and
cost-effective system (Fig. 1).
