DATASHEET
5. DEVICE DESCRIPTION
The SGTL5000 is a low power stereo codec with integrated headphone amplifier. It
is designed to provide a complete audio solution for portable products needing line-
in, mic-in, line-out, headphone-out, and digital I/O. Deriving it’s architecture from
best in class Freescale integrated products that are currently on the market, the
SGTL5000 is able to achieve ultra low power with very high performance and func-
tionality, all in one of the smallest footprints available. Target markets include por-
table media players, GPS units and smart phones. Features such as capless
headphone design and USB clocking mode (12MHz SYS_MCLK input) help lower
overall system cost.
In summary, SGTL5000 accepts the following inputs:
• Line input
• Microphone input, with mic bias (mic bias only available in 32QFN version)
• Digital I2S input
In addition, SGTL5000 supports the following outputs:
• Line output
• Headphone output
• Digital I2S output
The following digital audio processing is included to allow for product differentiation:
• Digital mixer
• SigmaTel Surround
• SigmaTel Bass Enhancement
• Tone Control, parametric equalizer, and graphic equalizer
The SGTL5000 can accept an external standard master clock at a multiple of the
sampling frequency (i.e. 256*Fs, 385*Fs, 512*Fs). In addition it can take non stan-
dard frequencies and use the internal PLL to derive the audio clocks. The device
supports 8kHz, 11.025kHz, 16kHz, 22.5kHz, 24kHz, 32KHz, 44.1kHz, 48kHz,
96kHz sampling frequencies.
