NVCSI -- Doubts in Datasheet

Hello All,
As per the below image,

Here,
Target Frequency 214 MHz (for RAW 8) 429 MHz (for RAW 8)

What is meaning of 429MHZ for RAW8?

-Thanks.

Please refer to the relevant info in module datasheet: Frequency Target: The parallel pixel processing rate, measured in pixels-per-clock (PPC), is increased to allow higher throughput and lower clock speeds. To support higher bandwidth without increasing the operating frequency, the host processes multiple pixels in one clock. NVCSI is capable of processing four PPCs when bits-per-pixel (BPP) is greater than 16, and eight PPC when BPP is less than or equal to 16.
