The 8545 is a low skew, high performance 1-to-4 LVCMOS/LVTTL-to-LVDS Clock Fanout Buffer and a member of the family of High Performance Clock Solutions from IDT. Utilizing Low Voltage Differential Signaling (LVDS) the 8545 provides a low power, low noise, solution for distributing clock signals over controlled impedances of 100Ω. The 8545 accepts a LVCMOS/LVTTL input level and translates it to 3.3V LVDS output levels. Guaranteed output and part-to-part skew characteristics make the 8545 ideal for those applications demanding well defined performance and repeatability.

Features

  • Four differential LVDS output pairs
