5.14 OpenLDI Interface General Timing Requirements

The DLPC23x-Q1 ASIC input interface supports a subset of the industry standard OpenLDI (FPD-Link I) interface (Open LVDS Display Interface Specification v0.95 - May 13, 1999). Specifically, from the standard, the ASIC supports the 24-bit, Single Pixel Format, using the Unbalanced Operating Mode and Pixel Mapping.
MIN NOM MAX UNIT
ƒclock Clock frequency, L1_CLK_P/N, L2_CLK_P/N 20.0 110 MHz
tp Clock period, PCLK 50% reference points 9.091 50 ns
tskew Skew Margin (between clock and data ) ƒclock = 85 MHz –400 (5) 0 400(5) ps
tskew_ports Clock to clock skew margin between ports on same ASIC, and between ports on different ASICs 1 clocks
tip0 Input data position 1 (tp / 7) – tskew (tp / 7) (tp / 7) + tskew ps
tip6 Input data position 2 2 * (tp / 7) – tskew 2 * (tp / 7) 2 * (tp / 7) + tskew ps
tip5 Input data position 3 3 * (tp / 7) – tskew 3 * (tp / 7) 3 * (tp / 7) + tskew ps
tip4 Input data position 4 4 * (tp / 7) – tskew 4 * (tp / 7) 4 * (tp / 7) + tskew ps
tip3 Input data position 5 5 * (tp / 7) – tskew 5 * (tp / 7) 5 * (tp / 7) + tskew ps
tip2 Input data position 6 6 * (tp / 7) – tskew 6 * (tp / 7) 6 * (tp / 7) + tskew ps
tjitter Input Jitter Tolerance
(cycle to cycle, peak to peak)		 100 ps
ƒspread Supported Spread Spectrum range percent of ƒclock rate –1%(1) +1%(2)
ƒmod Supported Spread Spectrum Modulation Frequency(3)(4) 25 65 kHz
(1) This value is limited by the minimum clock frequency for ƒclock (that is, if ƒclock = min clock freq, then ƒspread max = 0%).
(2) This value is limited by the maximum clock frequency for ƒclock (that is, if ƒclock = max clock freq, then ƒspread max = 0%).
(3) Modulation Waveforms supported: Sine and Triangle.
(4) Spread spectrum on OpenLDI interfaces was simulated, but not tested.
(5) t skew for other ƒclock values can be estimated by +/- tskew = -7.143 * ƒclock + 1007.1 - (tjitter - 100)
