CS8422
12.4.3 Serial Copy Management System (SCMS)
In Software Mode, the CS8422 allows read access to all the channel status bits. For consumer mode SCMS
compliance, the host microcontroller needs to read and interpret the Category Code, Copy bit and L bit ap-
propriately.
In Hardware Mode, the SCMS protocol can be followed by using the C bit serial output pin. See “Channel
Status and User Data Handling” on page 34 for more details.
12.5 Jitter Attenuation
Figure 36 shows the jitter attenuation characteristics of the CS8422 PLL. The AES3 and IEC60958-4 spec-
ifications state a maximum of 2 dB jitter gain.
