DCLK
Complementary Differential Clock Outputs. Used to synchronize following circuitry: Outputs A0–A7
are valid after DCLK’s rising edge. B0–B7 output data are valid after DCLK’s falling edge (see Figure 1
for output timing information).

CLK
Complementary Differential Clock Inputs. Can be driven from standard 10KH ECL with the following
considerations: Internally, pins 2, 62 and 3, 61 are the ends of a 50
Ω
transmission line. Either end
can be driven with the other end terminated with 50
Ω
to -2V. See

B7–B0
AData and BData Outputs. A0 and B0 are the LSBs, and A7 and B7 are the MSBs. AData and BData
outputs conform to ECL logic swings and drive 100

transmission lines. Terminate with 100
Ω

(120
Ω
for Tj > +100°C). See Figures 1–3.
