V-by-One® HS output data-rate
V-by-One® HS output data-rate is made of actual Pixel clock frequency.
At Low Frequency Mode, Data-rate is doubled.
Supported Data-rate is from 400Mbps to 4Gbps.
6.10 V-by-One® HS output Spread Spectrum
Spread Spectrum Clock Generation (SSCG) modulation is available to apply on V-by-One® HS output.
Table 21.
V-by-One® HS output Spread Spectrum settings
SSCG modulation frequency divider setting values, R_DIVVAL on Address 0x1010, to meet V-by-One® HS
standard 30kHz +/-0.5% are exemplified below.
