.. IDT85304-01 LOW SKEW, 1-TO-5 DIFFERENTIAL-TO-3.3V LVPECL MERCIAL AND INDUSTRIAL TEMPERATURE RANGES LOW SKEW, 1-TO-5 DIFFERENTIAL-TO-3.3V LVPECL FANOUT BUFFER Features : - Five differential 3.3V LVPECL outputs - Selectable differential CLK, x CLK, or LVPECL clock inputs - CLK, x CLK pair can accept the following differential input levels: LVDS, LVPECL, LVHSTL, SSTL, and HCSL - PCLK, x PCLK supports the following input types: LVPECL, CML, and SSTL - Maximum output frequency: 650MHz - Translates any single-ended input signal to 3.3V LVPECL levels with resistor bias on x CLK input - Output skew: 35ps (max.) - Part-to-part skew: as low as 150ps - Propagation delay: 2.1ns (max.) - 3.3V operating supply - Available in TSSOP package DESCRIPTION: The IDT85304-01 is a low skew, high performance 1-to-5 differential-to3.3V LVPECL clock generator-divider. It has two selectable clock inputs. The CLK/ x CLK pair can accept most standard differential input levels. The PCLK/ x PCLK pair can accept LVPECL, 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 IDT8530401 ideal for those applications that demand well-defined performance and repeatability.
