Overview
The WM9714CLGEFL/V is a highly integrated AC'97 audio codec designed for mobile computing. It features a stereo CODEC with 24-bit resolution, supporting DAC SNR of 94dB and ADC SNR of 87dB. The device includes an auxiliary mono DAC and a PCM voice interface. Operating voltages range from 1.8V to 3.6V for analog supplies and 1.71V to 3.6V for digital supplies. It supports input clocks from 2.048MHz to 78.6MHz via an internal PLL. The component is housed in a 48-lead QFN package (7x7mm) and operates within a temperature range of -25°C to +85°C.
Feature Summary
- Dual CODEC architecture supporting hi-fi stereo functions via AC link and voice functions via PCM SSP.
- Integrated headphone driver and speaker drivers enabling capless connections to reduce system component count.
- On-chip PLL generates audio clocks from a wide range of input frequencies.
- Seamless interface capabilities for wireless communication devices.
Applications
- Smartphones
- Personal Digital Assistants (PDA)
- Handheld and Tablet Computers
Procurement Notes
Verify the specific ordering suffix against the manufacturer's documentation to confirm packaging type. The CLGEFL/V designation indicates a lead-free 48-lead QFN package with a standard tray configuration. Confirm moisture sensitivity level and peak soldering temperature requirements prior to assembly to ensure compliance with IPC/JEDEC standards.
Selection Notes
Select this component for applications requiring a single-chip solution for both high-fidelity audio playback and voice communication. Ensure the host controller supports the AC'97 Rev 2.2 standard or utilizes the additional PCM interface for voice data. Verify that the available power supply rails match the specified 1.8V to 3.6V operating ranges for optimal performance.
Part Context
This part belongs to the Cirrus Logic WM9714L series of audio codecs. It is specifically engineered for portable electronic devices where space and power efficiency are critical constraints. The device integrates multiple audio paths and control interfaces into a compact form factor suitable for handheld systems.
Replacement Considerations
The WM9714CLGEFL/RV is a verified alternative offering identical electrical characteristics and functionality but supplied in tape and reel packaging instead of trays. Both variants share the same pinout and operational parameters.
