Overview

Description

The 621 is a low skew, single input to four output, clock buffer. The device operates from a single 1.2 to 1.8 volt supply and has a 3.3 volt tolerant input, making it ideal for level translation. 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

  • Low skew outputs (150 ps)
  • Packaged in 8-pin SOIC or 8-pin DFN (2x2mm)
  • RoHS 5 or RoHS 6 (lead-free) package
  • Low power CMOS technology
  • Operating voltages of 1.2 V to 1.8 V
  • Output Enable pin tri-states outputs
  • 3.3 V tolerant input clock
  • Industrial or commercial temperature ranges

  3. Forced break issue of Self-programming RL78

    Hi support team, I noticed that forced break is ignored while using the function "FSL_ChangeInterruptTable". (Occur lockup a debugger.) However, It's possible to break by a hardware or software break-point at RAM or ROM. After calling the function "FSL_RestoreInterruptTable" , forced break is enabled. This seems to ...
