285 views

Overview

Discover the W163, a state-of-the-art Spread Aware, Zero Delay Buffer that takes signal integrity and performance to new heights. With an operating voltage range of 1.8V to 3.3V and an extended industrial temperature range of -40°C to 85°C, this robust buffer is ideal for a variety of high-speed applications. Experience seamless synchronization, minimal delay variations, and unmatched reliability with the W163, revolutionizing your designs with superior accuracy.

The W163 comprises five-output zero delay buffers, incorporating a Phase-Locked Loop (PLL) that accurately replicates a time-varying signal into five identical copies. Through internal feedback, the PLL ensures that the outputs maintain precise phase alignment with the reference inputs.

Pin Definitions

Pin NoPin NameDescription
1REFReference Input: The output signals Q0:3 will be synchronized to this signal
unless the device is programmed to bypass the PLL
2, 3, 5, 7Q0:3Outputs: These signals will be synchronous and of equal frequency to the signal
input at pin 1.
4GNDGround Connections: Connect all grounds to the common system ground
plane
6VDDPower Connections: Connect to 3.3V. Use ferrite beads to help reduce noise
for optimal jitter performance
8QFBFeedback Output: This output signal does not vary from signals Q0:3 in function,
but is noted as the signal used to establish the propagation delay of nearly 0.

Applications

  • Clock signal synchronization in high-speed communication systems
  • Precision timing circuits requiring minimal delay variations
  • Memory interfaces requiring enhanced signal integrity
  • Spread Spectrum Frequency Timing Generator (SSFTG) integration
