Description :

The TEA5767 is a single-chip electronically tuned FM stereo radio for low-voltage applications with fully integrated Intermediate Frequency (IF) selectivity and demodulation. The radio is completely adjustment-free and only requires a minimum of small and low cost external components. The radio can be tuned to the European, US, and Japanese FM bands.

Pinouts

Features

1. High sensitivity due to integrated low-noise RF input amplifier
2. FM mixer for conversion to IF of the US/Europe (87.5 MHz to 108 MHz) and Japanese (76 MHz to 91 MHz) FM band
3. Preset tuning to receive Japanese TV audio up to 108 MHz
4. RF Automatic Gain Control (AGC) circuit
5. LC tuner oscillator operating with low cost fixed chip inductors
6. FM IF selectivity performed internally
7. No external discriminator needed due to fully integrated FM demodulator
8. Crystal reference frequency oscillator; the oscillator operates with a 32.768 kHz clock crystal or with a 13 MHz crystal and with an externally applied 6.5 MHz reference frequency

24-bit, 192kHz Stereo CODEC WM8778

Description

The WM8778 is a high performance, stereo audio CODEC. It is ideal for surround sound processing applications for home hi-fi, DVD-RW and other audio visual equipment. The stereo 24-bit multi-bit sigma delta ADC has programmable gain with automatic level control. Digital audio output word lengths from 16-32 bits and sampling rates from 32kHz to 96kHz are supported. A stereo multi-bit sigma delta DAC is used with digital audio input word lengths from 16-32 bits and sampling rates from 32kHz to 192kHz. A multiplexor after the DAC allows the selection of either an external analogue input or DAC playback into the line outputs. The WM8778 supports fully independent sample rates for the ADC and DAC. The audio data interface supports I2S, left justified, right justified and DSP formats. The device is controlled in software via a 2 or 3 wire serial interface which provides access to all features including volume controls, mutes, and de-emphasis facilities. It can also be controlled in hardware which gives access to the most commonly used features. Control interface selection is done via the MODE pin (trilevel).
