WM8753L
Hi-Fi and Telephony Dual CODEC
DESCRIPTION
The WM8753L is a low power, high quality stereo CODEC
with integrated Voice CODEC designed for portable digital
telephony applications such as mobile phone, or headset
with hi-fi playback capability.
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.
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 256fs rates like 12.288MHz and
24.576MHz. Internal PLLs generate all required clocks for
both Voice and hi-fi converters. If audio system clocks
already exist, the PLLs may be committed to alternative
uses.
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.

POWER CONSUMPTION
The power consumption of the WM8753L depends on the following factors.
Supply voltages: Reducing the supply voltages also reduces supply currents, and therefore results in
significant power savings.
Operating mode: Power consumption is lower in mono modes than in stereo, as one ADC / DAC /
PGA is switched OFF. It is also reduced when the device is used for playback only (ADC off) or for
recording only (DAC off). Unused outputs should be switched off (for example, when line out is not
used, do not enable the LINE outputs).
Headphone volume: At high volume, the power dissipated in the headphone itself is greater than the
power consumption of the WM8753L. High headphone volume also increases the power consumption
of the on-chip headphone drivers.
