Application Scenarios & Design Considerations

FAST CMOS BUFFER/CLOCK DRIVER

Alternative Part Number

  • CDCVF2505PWR --: PLL-based zero-delay clock buffer in TSSOP package with similar fanout and skew performance, widely available and pin-compatible in function.
  • CY2305SC-1 --: Zero-delay clock buffer with multiple outputs, comparable operating frequency and supply voltage, suitable drop-in functional replacement.
  • NB3N551DG --: Low-skew clock fanout buffer with similar output count and voltage range, offered in SOIC package as a practical alternative.
  • PI49FCT805PY --: Same 49FCT805 clock buffer function in the same PY package, widely used as a drop-in second source for the IDT part.
  • CY2DP1504ZXC --: Comparable low-skew clock fanout buffer with similar output count and supply voltage, suitable functional replacement with layout review.
  • NB6L11SMNG --: Differential clock fanout buffer offering similar fanout and low skew performance, usable as an alternative with minor design verification.
