DCLK-to-DATA[] Ratio (r) for FPP Configuration
Fast passive parallel (FPP) configuration requires a different DCLK-to-DATA[] ratio when you turn on encryption or the compression feature.
Depending on the DCLK-to-DATA[] ratio, the host must send a DCLK frequency that is r times the DATA[] rate in byte per second (Bps) or word per second (Wps). For example, in FPP ×16 where the r is 2, the DCLK frequency must be 2 times the DATA[] rate in Wps.
Configuration Scheme | Encryption | Compression | DCLK-to-DATA[] Ratio (r) |
---|---|---|---|
FPP (8-bit wide) | Off | Off | 1 |
On | Off | 1 | |
Off | On | 2 | |
FPP (16-bit wide) | Off | Off | 1 |
On | Off | 2 | |
Off | On | 4 | |
FPP (32-bit wide) | Off | Off | 1 |
On | Off | 4 | |
Off | On | 8 |
