Abstract
One of most common and difficult challenge when creating a single SoC with digital (sub)sections is caused by the various master clock (MCLK) frequencies that each individual IC had originally. There are several methods to solve this, but when constraint by price and power consumption, the design engineers must find the optimum one. The sample rate converters (SRC) are an example of solution that can simplify the architecture in some of these cases. However, even for the SRCs themselves, we need to come up with novel and efficient architectures. This paper presents such an example from mobile phones chips on how to successfully mix on the same silicon, an audio sigma-delta DAC which should support all the standard audio rates using a 13MHz MCLK frequency imposed by the RF section incorporated inside the same chip. The document will go from showing the top-level digital signal processing down to the actual hardware implementation. |
