since FPDLINK used NRZ coding, if the fpdlink rate is 2gbps, the upper frequency is 1GHZ,about the lower frequency, what is the lower frequency?
您好,为了方便沟通,我们直接用中文吧。
941的line rate范围为0.875~3.675Gbps/lane,即信号频率为0.4375~1.8375GHz/lane。
您这里指的upper或lower frequency具体指的是什么频率?是不是FPD link的line rate?即我所说的0.4375~1.8375GHz/lane?
最低不是0Hz,每个 PCLK 会把 24bit RGB 数据、控制信号、时钟信号编码成为 35bit 数据,而PCLK的频率范围single link为25Mhz~105Mhz,dual link模式下为50Mhz~210Mhz。line rate 和 PCLK 之间存在固定的 35 倍关系,Line rate= fPCLK *35。 所以可以计算得到line rate(min)=25*35=875Mbps, line rate(max)=3675Mbps.
