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.

Applications

• FM stereo receiver in MP3 players, portable audio devices

• Miniature FM radio

• Mini- and micro-sized audio systems

• Home Hi-Fi

Key features

• Only 18 external components (19 passive components

• No alignments necessary

• Fully integrated FM IF selectivity and demodulation

• Signal dependent mono / stereo blend (stereo noise cancelling)

• Adjustment free stereo decoder

• Soft mute and signal dependent high cut control (HCC)

• Autonomous Search Tune (AST) to decrease bus communication

• Software switchable low / high injection local oscillator

• Two software programmable ports

• 32.768 kHz / 6.5 MHz / 13 MHz software switchable oscillator

• Package/interface options

• Standby mode switched via bus

• 2.5 V minimum supply voltage

• Automotive temperature range (at 5 V

and mobile phones

replaced by silicon)

TEA5767/68

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.
