PI6CB3320xxA Series Clock Buffers

Diodes Inc. clock buffers offer low-additive phase jitter, which enhances system timing margin in high-speed connectivity applications

Image of Diodes Incorporated PI6CB3320xxA Series Clock BuffersThe PI6CB3320xxA series from Diodes Inc. consists of PCIe 6.0 clock buffers with 20, 16, 13, 12, 8, and 4 channels of low-power HCSL output with on-chip termination of 85 W or 100 W output impedance. The series has very low 3 fs to 4 fs additive phase jitter and supports a flexible start-up power sequence, loss of input signal detection, power-down tolerant input pins, and automatic output clock parking upon loss of input signal. Their individual channel OE input provides flexible power management. Output clock frequencies up to 400 MHz are supported. The PI6CB3320xxA family is available in various small-footprint QFN and LGA packages ranging from 4 mm x 4 mm to 9 mm x 9 mm.

Features
  • 3 fs to 4 fs additive phase jitter minimizes phase noise for increased system timing margins
  • Individual OE pin for each output allows dynamic routing and enhances power saving
  • Flexible start-up power simplifies system design and ensures well-defined system behavior under various power sequencing scenarios
 
  • Available in 20-, 16-, 13-, 12-, 8-, and 4-output variants that support various system clock tree design requirements
  • On-chip termination saves up to 80 external resistors, reducing BOM cost, saving board space, and simplifying PCB layout
Applications
  • Servers
  • Data systems
 
  • Surveillance systems
