Philips Semiconductors
Philips Semiconductors’ digitally tuned TEA5767/68 FM stereo
receiver IC is based on an innovative architecture concept that
simplifies radio design, significantly reducing the number of external
components. Delivering the highest performance levels, this one-chip
radio solution occupies minimal PCB area (9x9 mm) making it ideal
for all space-critical and low voltage applications such as mobile
phones and MP3 players.
single-chip FM stereo radio
The single-chip TEA5767/68 is a miniature, digitally tuned radio IC
that utilizes an entirely new radio architecture concept that replaces
passive components and complex circuitry, with on-board silicon,
drastically reducing the overall bill of materials and making design-in
easier. It requires zero external alignments, resulting in shorter design
times and lower manufacturing costs due to simplified component
placement and reduced logistics overhead. Also, being adjustment free,
it delivers increased quality and reliability, both in manufacture and
throughout its lifetime in your end application.
As well as offering increased functionality in handheld devices, the
radio IC is ideal for integration in a wide range of applications, where
its minimal interaction with the rest of your application helps avoid
reception / transmission interference. The TEA5767/68 also features
very low power consumption and its small footprint makes it ideal for
applications where board space is at a premium.
Capable of tuning to European, US and Japanese FM bands, the
TEA5767/68 does not need an external FM discriminator and handles
IF selectivity entirely on-chip.
