12 Bit,2-to-1,3.3V,2.5V LVPECL Clock Buffer

The 85352I is a 12 bit, 2-to-1 LVPECL Clock Buffer. Individual input select controls support independent multiplexer operation from a common clock input source. Clock inputs accept most standard differential levels. The 85352I is characterized at full 3.3V or mixed 3.3V core/2.5V output operating supply modes.

Features

  • Twelve, 2-to-1 multiplexers with LVPECL outputs
  • Selectable differential CLKx, nCLKx input pairs
  • CLK, nCLK pair can accept the following differential input levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL
  • Maximum output frequency: 700MHz
  • Individual select control for each multiplexer
  • Select inputs accept LVCMOS / LVTTL levels
  • Propagation delay: 2ns (maximum)
  • Additive Phase Jitter, RMS: 0.21ps (typical), 3.3V
  • Full 3.3V or mixed 3.3V core/2.5V output supply
  • -40°C to 85°C ambient operating temperature
  • Available in lead-free (RoHS 6) package
