| Can anyone tell me how to extract the clock from incoming SPDIF DAta ? |

| Use an SPDIF interface chip (like the CS8414) and grab the clock line off of that ;) |

| I beleive this chip recovers the clock from the incoming data using a PLL. I wanted to know whether there is any other method also to recover the clock. |

Hi,
You may use the CS8415 as it uses the preamble to feed the PLL circuit. At leat the data dependancy of the jiter decreases.
If you want to do a better job, you may consider a secondary PLL circuit with much lower cut off frequency and a decent VCXO.
In my designs I obtain about 8 ps jitter.
