8 / 18 page Audio DSP CDCS504-Q1 TAS6424 SCLK (2.816 MHz) SCLK (2.816 MHz) Other Signals MCLK (11.264 MHz) Copyright © 2017, Texas Instruments Incorporated 8 CDCS504-Q1 SCAS951 – APRIL 2017 www.ti.com Product Folder Links: CDCS504-Q1 Submit Documentation Feedback Copyright © 2017, Texas Instruments Incorporated 9 Application and Implementation NOTE Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information The CDCS504-Q1 is a clock buffer or multiplier for automotive amplifiers and infotainment. It is fit for the TAS6424-Q1, a four-channel, class-D, digital-input audio-amplifier, when the applications are without available MCLK. See Figure 6 for more details. 9.2 Typical Application Figure 6. Clock for Automotive Amplifiers 9.2.1 Design Requirements The CDCS504-Q1 is supplied with a single-power 3.3 V. The device supports minimum input frequency to 2 MHz. For maximum input frequency, it is 32 MHz in ×1 mode, and 27 MHz in ×4 mode. The input clock is LVCMOS type and should satisfy requirements in the Recommended Operating Conditions. 9.2.2 Detailed Design Procedure In some applications, the clock input for CDCS504-Q1 is not always presented. In case there is an unexpected clock output without clock input, TI recommends setting OE pin to low. When it gets clock input ready, set OE pin to high to get expected clock output. If the other application presents continuous clock input for CDCS504-Q1, the OE pin could be floated, internal pullup brings output enable, or an external pullup circuits could be used fixedly. 9.2.2.1 Custom Design With WEBENCH® Tools Click here to create a custom design using the CDCS504-Q1 device with the WEBENCH® Power Designer. 1. Start by entering the input voltage (VIN), output voltage (VOUT), and output current (IOUT) requirements. 2. Optimize the design for key parameters such as efficiency, footprint, and cost using the optimizer dial. 3. Compare the generated design with other possible solutions from Texas Instruments. The WEBENCH Power Designer provides a customized schematic along with a list of materials with real-time pricing and component availability. |
