SY898530U 500MHz 1:16 3.3V-to-2.5/3.3V LVPECL Fanout Buffer General Description Features The SY898530U is a 1:16 Fanout buffer which can accept 16 Differential 2.5V/3.3V LVPECL outputs most standard differential logic levels and outputs the Differential CLK inputs. Accepts LVDS, LVPECL, signal as a differential 2.5V or 3.3V LVPECL signal. The LVHSTL, SSTL, HCSL logic levels part can amplify input signals as small as 150mVpp to the Translates any single-ended input signal to 2.5/3.3V full LVPECL output swing. The SY898530U is well suited LVPECL levels with a resistor bias on /CLK input for clock distribution applications which demand versatility 500MHz maximum output frequency and low-skew performance. It is pin-to-pin compatible with IDTs ICS8530 fanout buffer. <50ps output skew The SY898530U operates from a 3.3V 5% core power <250ps part-to-part skew supply and a 2.5V 5% or a 3.3V 5% output supply. The <2ns propagation delay SY898530U is guaranteed over the full commercial 3.3V Core, 2.5/3.3V output operating supply temperature range (0C to +70C). It is available in a 48- 0C to +70C operating temperature pin TQFP lead-free package. Available in 48-pin TQFP package Data sheets and support documentation can be found on Pin-to-pin compatible with ICS8530 Micrels web site at www.micrel.com.
