3.3 V Zero Delay Buffer


  • Zero input output propagation delay, adjustable by capacitive load on FBK input
  • Multiple configurations
  • Multiple low-skew outputs
    • 45-ps typical output-output skew (–1)
    • Two banks of four outputs that can be tristated by two select inputs
  • 10 MHz to 140 MHz operating range
  • 65-ps typical cycle-to-cycle jitter (–1, –1H)
  • Advanced 0.65-μm complementary metal oxide semiconductor (CMOS) technology
  • Space-saving 16-pin small outline integrated circuit (SOIC) package
  • 3.3-V operation
  • Spread Aware

Functional Description

The CY23S08 is a 3.3-V zero delay buffer designed to distribute high-speed clocks in PC, workstation, datacom, telecom, and other high-performance applications.

The part has an on-chip PLL which locks to an input clock presented on the REF pin. The PLL feedback must be driven into the FBK pin, and obtained from one of the outputs. The input-to-output propagation delay is less than 350 ps and output-to-output skew is less than 250 ps.
