  • Designed for Signaling Rates up to:
    • 500-Mbps Receiver
    (1)
  • Operates From a 1.8-V or 2.5-V Core Supply
  • Available in 1.5-mm × 2-mm UQFN Package
  • Bus-Terminal ESD Exceeds 2 kV (HBM)
  • Low-Voltage Differential Signaling With Typical Output Voltages of 350 mV Into a 100-Ω Load
  • Propagation Delay Times
    • 2.1 ns Typical Receiver
  • Power Dissipation at 250 MHz
    • 40 mW Typical
  • Requires External Failsafe
  • Differential Input Voltage Threshold Less Than 50 mV
  • Can Provide Output Voltage Logic Level (3.3-V LVTTL, 2.5-V LVCMOS, 1.8-V LVCMOS) Based on External VDD Pin, Thus Eliminating External Level Translation
(1) The signaling rate of a line is the number of voltage transitions that are made per second expressed in the units bps (bits per second)

2 Applications
