WM8753L

Hi-Fi and Telephony Dual Codec

DESCRIPTION

FEATURES

The WM8753L is a low power, high quality stereo Codec with

integrated PCM CODEC designed for portable digital telephony

applications such as mobile phone, or headset with Hi-Fi

playback capability.

•

Hi-Fi DAC: interfaced over I²S type link

Audio sample rates: 8, 11.025, 16, 22.05, 24, 32, 44.1, 48,

DAC SNR 98dB, THD -84dB (‘A’ weighted @ 48kHz)

ADC SNR 95dB, THD -82dB (‘A’ weighted @ 48kHz)

On-chip Headphone Driver with cap-less output option

The device integrates dual interfaces to two differentially

connected microphones, and includes drivers for speakers,

headphone and earpiece. External component requirements

are reduced as no separate microphone or headphone

amplifiers are required, and Cap-less connections can be made

to all loads. Advanced on-chip digital signal processing

performs tone control, Bass Boost and automatic level control

for the microphone or line input through the ADC. The two

ADCs may be used to support Voice noise cancellation in a

partnering DSP, or for stereo recording.

40mW output power on 16Ω / 3.3V

with 16Ω load: SNR 90dB, THD –75dB

with 10kΩ load: SNR 94dB, THD –90dB

•

On-chip speaker driver with 0.5W into 8R

PCM Codec: interfaced over PCM interface

supports sample rates from 8ks/s to 48ks/s

ADC and DAC SNR 82dB, THD -74dB

Two Differential Microphone Interfaces

Dual ADCs support noise cancellation in external DSP

Programmable ALC / Noise Gate

The WM8753L Hi-Fi DAC can operate as a master or a slave,

with various master clock frequencies including 12 or 24MHz

for USB devices, 13MHz or 19.2MHz for cellular systems, or

standard 256f_srates like 12.288MHz and 24.576MHz. Internal

PLLs generate all required clocks for both PCM and Hi-Fi

converters. If audio system clocks already exist, the PLLs may

be committed to alternative uses.

•

Low-noise bias supplied for electret microphones

Other features

•

On-chip PLLs supporting 12, 13, 19.2MHz and other clocks

Cap-less connection options to headphones, earpiece, spkr.

Low power, low voltage

1.8V to 3.6V (digital core: 1.42V to 3.6V)

power consumption <20mW all-on with 2V supplies

<12mW for PCM CODEC operation

The WM8753L operates at a nominal supply voltage of 2V,

although the digital core can operate at voltages down to 1.42V

to save power, and the maximum for all supplies is 3.6 Volts.

Different sections of the chip can also be powered down under

software control.

•

7x7x0.9mm QFN package

APPLICATIONS

•

MP3 Player / Recorder mobile phone

Bluetooth stereo headset
