Features

  • Automatically detects the presence or absence of input clocks and switches clock modes
  • One open-drain CC_IR output indicates PCIe clock mode
  • Integrated crystal option available (Q option)
  • Two 100MHz Low-power HCSL (LP-HCSL) outputs; 100Ω output impedance
  • Integrated terminations on DIF outputs save 8 resistors
  • 201, 301 configurations for SRnS (IR) or CC architectures default to 0% SSC
  • 202, 302 configurations for SRIS (IR) or CC architectures default to -0.5% SSC
  • SMBus-selectable -0.25% SSC
  • Choice of 25MHz or 33 1/3MHz reference clock
  • REF clock output saves external XO
  • 2.5V or 3.3V operating voltage (VDDREF is 1.8V)
  • 4mm × 4mm 28-VQFP-N package with external crystal
  • 4mm × 4mm 28-LGA package with optional internal crystal
  • Easy AC coupling to other logic families, see application note AN-891
  • For devices with 85Ω output impedance, see 9FGL6251

Description

The 9FGL6241 is an intelligent buffer/clock generator tailored for single and dual-ported nVME SSDs. It supports Common (CC) and Independent Reference (IR) clocking architectures and is ideal for U.2 and M.2 form factors. The device is also useful in PCIe master/slave and clock multiplexing applications, with an internal clock generator as a third input channel.
