The Renesas Electronics 85104I is a low skew, high performance 1-to-4 Differential/LVCMOS-to-0.7V HCSL Fanout Buffer. The 85104I has two selectable clock inputs. The CLK0, nCLK0 pair can accept most standard differential input levels. The single-ended CLK1 can accept LVCMOS or LVTTL input levels. The clock enable is internally synchronized to eliminate runt clock pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin. Four 0.7V differential HCSL outputs
Selectable differential CLK0, nCLK0 or LVCMOS inputs
CLK0, nCLK0 pair can accept the following differential
input levels: LVPECL, LVDS, LVHSTL, HCSL
CLK1 can accept the following input levels:
LVCMOS or LVTTL
Maximum output frequency: 500MHz
Translates any single-ended input signal to 3.3V
HCSL levels with resistor bias on nCLK input
Output skew: 100ps (maximum)
Part-to-part skew: 600ps (maximum)
Propagation delay: 3.2ns (maximum)
Additive phase jitter, RMS: 0.22ps (typical)
