Preliminary DS60001270C-page 19CY9203.0 APPLICATION GUIDELINESThis section describes the power-up sequence and theRF guidelines recommended by Microchip.3.1 Power Sequencing and Reset TimingThe power sequencing during power on should startwith the highest voltage rail. The power sequencingshould progress from the higher voltage rail to thelower voltage rail, i.e power-up 3.3V, 2.5V, 1.8V, andthen 1.2V with a delay of 2 ms between each power rail.During power-down, the power sequencing should bein the reverse direction, i.e., remove 1.2V, 1.8V, 2.5V,and then 3.3V. The power-up sequence is mandatoryand the power-down sequence is preferred, butoptional. Figure 3-1 illustrates the power-up timing.FIGURE 3-1: POWER-UP SEQUENCE3.2 RF ConsiderationsThe overall performance of the system, RF, andWi-Fi/BT is significantly affected by the product design,environment and application. It is the responsibility ofthe product designer to ensure system level shielding(if required) and to verify the performance of the givenproduct features and applications.The Wi-Fi/BT performance will be affected by the RFenvironment surrounding the CY920 module. Considerthe following precautions for optimal Wi-Fi/BTperformance:• The CY920 module is positioned in a noise-free RF environment, i.e, away from high frequency clock signals and any other sources of RF energy. • The antenna is not shielded by any metal objects, such as loudspeakers or any other metal parts.• The power supplies are clean and noise-free.Note: This data sheet summarizes the featuresof the CY920 network media module.
