Low Skew, 1-to-9, Differential-to-3.3V, 2.5V LVPECL/ECL Fanout Buffer ICS853S031I General Description The ICS853S031I is a low skew, high performance 1-to-9 Differential-to-2.5V/3.3V LVPECL/ECL Fanout Buffer. The ICS853S031I has two selectable clock inputs. The CLK, nCLK pair can accept most standard differential input levels. The PCLK, nPCLK pair can accept LVPECL, LVDS, CML or SSTL input levels. The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin. Guaranteed output and part-to-part skew characteristics make the ICS853S031I ideal for high performance workstation and server applications. Features • Nine differential 2.5V, 3.3V LVPECL/ECL outputs • Selectable differential CLK, nCLK or LVPECL clock inputs • CLK, nCLK pair can accept the following differential input levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL • PCLK, nPCLK supports the following input types: LVPECL, LVDS, CML, SSTL • Output frequency: 1.6GHz (maximum) • Translates any single-ended input signal (LVCMOS, LVTTL, GTL) to 3.3V LVPECL levels with resistor bias on nCLK or nPCLK inputs • Output skew: 20ps (typical) • Part-to-part skew: 90ps (typical) • Propagation delay: 885ps (typical), PCLK • LVPECL mode operating voltage supply range: VCC = 2.375V to 3.465V, VEE = 0V • ECL mode operating voltage supply range: VCC = 0V, VEE = -3.465V to -2.375V • -40°C to 85°C ambient operating temperature • Available lead-free (RoHS 6) package Q0 nQ0 Q1 nQ1 CLK_SEL CLK_EN CLK nCLK 0 1 Pulldown Pullup Pullup Pulldown Q2 nQ2 Q3 nQ3 PCLK nPCLK Pulldown Pullup Q4 nQ4 Q5 nQ5 Q6 nQ6 Q7 nQ7 Q8 nQ8 D LE Q 9 10 11 12 13 14 15 16 32 31 30 29 28 27 26 25 1 2 3 4 5 6 7 8 24 23 22 21 20 19 18 17 VCC CLK nCLK CLK_SEL PCLK nPCLK VEE CLK_EN VCCO Q3 nQ3 Q4 nQ4 Q5 nQ5 VCCO ICS853S031I 32-Lead LQFP 7mm x 7mm x 1.4 mm package body Y Package Top View Pin Assignment Block Diagram |
