Application Scenarios & Design Considerations

PCI-EXPRESS CLOCK SOURCE

Alternative Part Number

  • SI5330B-B-GM --: Clock buffer/fanout device with similar function and package, widely used as an IDT clock distribution alternative.
  • NB3N5573DTG --: Clock fanout buffer with comparable output count and supply voltage, direct functional replacement for clock distribution applications.
  • CDCLVC1104PWR --: Low-jitter clock buffer offering similar fanout and voltage compatibility, suitable as a cross-reference substitute.
  • NB3N5573DTR2G --: Clock generator/fanout buffer in the same functional class with similar output drive and supply voltage, commonly used as a drop-in replacement for ICS557-series clock devices.
  • SI5338B-B-GM --: Versatile clock generator with programmable outputs that can be configured to match the ICS557G-03LFT output frequencies and interface levels.
  • CDCE913PWR --: Low-jitter clock synthesizer with similar supply range and output capability, suitable as a functional substitute when the exact ICS part is unavailable.
