w WM8753-6117-FL48-M-REV1 Example Configurations DOC TYPE: EXAMPLE CONFIGURATIONS BOARD REFERENCE: WM8753-6117-FL48-M-REV1-REV1 BOARD TYPE: Mini Board WOLFSON DEVICE(S): WM8753 DATE: November 2008 DOC REVISION: Rev1.0 INTRODUCTION The WM8753-6117-FL48-M-REV1 Mini Board is compatible with the 6117-EV1 customer evaluation board and together provide a complete hardware platform for evaluation of the WM8753. The WM8753 Mini Board can also be used independently and connected directly to a processor board using flying wires or appropriate headers. This document will cover both, but performance data will be based on the Wolfson “system” with 6117-EV1 motherboard. Configurations covered are listed below: • DAC Playback (Hi-Fi) to 32Ω Headphone on L/HPOUT L/R • ADC Record (Hi-Fi) from differential microphone (MIC1) • DAC Playback (Voice I/F) to 32Ω Headphone on L/HPOUT L/R • ADC Record (Voice I/F) from differential microphone (MIC1) This document should be used as a starting point for evaluation of WM8753 but it will not cover every possible configuration. Assumptions: 1. The user is familiar with the 6117-EV1 main board and that the board is configured correctly for the path of interest (see related documents below). 2. The user has setup WISCE as per instruction and has control of the DUT (register settings provided in WISE install file) Related documents: 1.

This “system” is the reference platform for measurement data contained in this document. Please note that only a limited number of usage modes will be covered. DAC PLAYBACK (HI-FI) TO 32Ω HEADPHONE ON L/HPOUT L/R The following section details board configuration for stereo DAC playback to 32ohm headphone on L/HPOUT L/R. It should be noted that L/HPOUT L/R outputs are routed to a headphone jack socket on the WM8753 Mini board and also to phono connectors and a speaker terminal block on the 6117EV1 main board. For the purpose of this test the mini board headphone jack socket was used with 32ohm loads applied.
