1TTL input values are 0 to 3 volts, with input rise/fall times ≤ 3 ns, measured between the 10% and 90% points. ECL inputs (CLOCK, CLOCK) are
VAA–0.8 V to VAA–1.8 V, with input rise/fall times ≤ 2 ns, measured between the 10% and 90% points. Timing reference points at 50% for inputs and out-
puts. Analog output load ≤ 10 pF. Databus (D0–D9) loaded as shown in Figure 1. Digital output load for LOADOUT, PRGCKOUT, SCKOUT, I PLL and
SYNCOUT ≤ 30 pF.
2± 5% for all versions.
3Temperature range (TMIN to TMAX): 0°C to +70°C; TJ (Silicon Junction Temperature) ≤ 100°C.
4Pixel Port consists of the following inputs: Pixel Inputs: RED [A, B, C, D]; GREEN [A, B, C, D]; BLUE [A, B, C, D], Palette Selects: PS0 [A, B, C, D]; PS1
[A, B, C, D]; Pixel Controls: SYNC, BLANK; Clock Inputs: CLOCK, CLOCK, LOADIN, SCKIN; Clock Outputs: LOADOUT, PRGCKOUT, SCKOUT.
5τ is the LOADOUT Cycle Time and is a function of the Pixel CLOCK Rate and the Multiplexing Mode: 1:1 multiplexing; τ = CLOCK = t1 ns. 2:1 Multi-
plexing; τ = CLOCK × 2 = 2 × t1 ns. 4:1 Multiplexing; τ = CLOCK × 4 = 4 × t1 ns.
6These fixed values for Pipeline Delay are valid under conditions where t 10 and τ-t11 are met. If either t10 or τ-t11 are not met, the part will operate but the Pipe line De-
lay is increased by 2 additional CLOCK cycles for 2:1 Mode and is increased by 4 additional CLOCK cycles for 4:1 Mode, after calibration is performed.
7Output delay measured from the 50% point of the rising edge of CLOCK to the 50% point of full-scale transition. Output rise/fall time measured between the 10%
and 90% points of full-scale transition. Transition time measured from the 50% point of full-scale transition to the output remaining within 2% of the final output
value (Transition time does not include clock and data feedthrough).
8t23 and t24 are measured with the load circuit of Figure 1 and defined as the time required for an output to cross 0.4 V or 2.4 V.
9t25 is derived from the measured time taken by the data outputs to change by 0.5 V when loaded with the circuit of Figure 1. The measured number is then extrapo-
lated back to remove the effects of charging the 100 pF capacitor. This means that the time, t 25, quoted in the Timing Characteristics is the true value for the device
and as such is independent of external databus loading capacitances.
Specifications subject to change without notice.
