The Audio PLL is a high-resolution fractional-N digital PLL specifically designed for low jitter operation. In audio applications, the CLK_AUDIO output pin typically serves as the Master clock frequency generator for external components such as Audio DAC, Audio ADCs, or Audio Codecs, thus saving one crystal on the board.. The reference clock of the Audio PLL is the fast crystal …

3.1.1. Random Jitter (RJ) The jitter generated within a PLL is primarily band limited random jitter. In addition white noise on the PLL supplies can be translated into random jitter at the PLL output. Random jitter comes from processes that are truly random such …

audio frequencies. They operate at 10MHz or other general purpose frequencies. The circuitry required for converting to audio clock rates (typically PLL) adds jitter. From a technology standpoint, meeting and exceeding clock accuracy requirements for audio is not particularly challenging. However, meeting the jitter requirements is a ...

For example in the recent CS8416 Digital Audio Interface Receiver "the PLL has been designed to only use the preambles of the biphase encoded stream to provide lock update information to the PLL", according to the Crystal/Cirrus data sheet: "This results in the PLL being immune to data dependent jitter effects because the preambles do not vary ...

Although these systems can implement a fractional-N divider PLL to create the desired audio MCLK frequency, such PLL-based frequency references usually have multiple reference frequency spurs and substantial low-frequency jitter. Moreover, these PLL-based frequency references often cannot get the jitter low enough for the application without ...
