553S - Low Skew 1 to 4 Clock Buffer
Improved jitter performance, smaller package, 1.8V to 3.3V supply voltage

The 553 is a low skew, single input to four output, clock buffer. Part of IDT's ClockBlocksTM family, this is our lowest skew, small clock buffer. See the 552-02 for a 1 to 8 low skew buffer. For more than eight outputs, see the MK74CBxxx BuffaloTM series of clock drivers. IDT makes many non-PLL and PLL based low skew output devices as well as Zero Delay Buffers to synchronize clocks. Contact us for all of your clocking needs.

Features

  • Extremely low skew outputs (50 ps maximum)
  • Packaged in 8-pin SOIC
  • Pb (lead) free package
  • Low power CMOS technology
  • Operating voltages of 2.5 V to 5 V
  • Output Enable pin tri-states outputs
  • 5 V tolerant input clock
  • Commercial (0 to +70°C) and Industrial (-40 to +85°C) temperature ranges available
