NXP SGTL5000XNLA3

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 LINEIN, mic-in, LINEOUT, headphone-out, and digital I/O. Deriving it’s architecture from best in class NXP integrated products that are currently on the market, the SGTL5000 is able to achieve ultra low power with very high performance and functionality, all in one of the smallest footprints available. Target markets include portable media players, GPS units and smart phones. Features such as capless headphone design and USB clocking mode (12 MHz SYS_MCLK input) help lower overall system cost.

In summary, the SGTL5000 accepts the following inputs:

• Line input

• Microphone input, with mic bias

• Digital I²S input

• Line output

• Headphone output

• Digital I²S output

The following digital audio processing is included to allow for product differentiation:

• Digital mixer
• NXP Surround
• NXP Bass Enhancement
• Tone Control, parametric equalizer, or graphic equalizer

The SGTL5000 can accept an external standard master clock at a multiple of the sampling frequency (i.e. 256Fs, 385Fs, 512*Fs)
