9FGL6251 - Intelligent PCIe Clock Buffer/Generator

Download the 9FGL6251 datasheet PDF. This datasheet also covers the 9FGL6241 variant, as both devices belong to the same intelligent pcie clock buffer/generator family and are provided as variant models within a single manufacturer datasheet.

General Description

The 9FGL6241 / 9FGL6251 are intelligent buffer/clock generators tailored for single and dual-ported nVME SSDs.

They support Common (CC) and Independent Reference (IR) clocking architectures and are ideal for U.2 and M.2 form factors.

Key Features

  • Two 100MHz Low-Power HCSL (LP-HCSL) outputs with Zo = 100Ω or 85Ω.
  • One 33 1/3MHz or 25MHz 1.8V LVCMOS REF output.
  • One open drain CC_IR output indicates PCIe clock mode Features.
  • Supports single or dual-ported nVME drives.
  • Automatically detects presence or absence of input clocks.
  • Integrated terminations on LP-HCSL outputs save 8 resistors.
  • Choice of spread off (0% SRnS) or spread on (-0.5% SRIS) de.

Intelligent PCIe Clock Buffer/Generator for SSD 9FGL6241 / 9FGL6251 Datasheet Description The 9FGL6241 / 9FGL6251 are intelligent buffer/clock generators tailored for single and dual-ported nVME SSDs. They support Common (CC) and Independent Reference (IR) clocking architectures and are ideal for U.2 and M.2 form factors. The devices are also useful in PCIe master/slave and clock multiplexing applications, with an internal clock generator as a third input channel. Typical Applications ▪ 1 × 4 and 2 × 2 nVME SSDs ▪ 3:2 PCIe clock multiplexing Output Features ▪ Two 100MHz Low-Power HCSL (LP-HCSL) outputs with Zo = 100Ω or 85Ω ▪ One 33 1/3MHz or 25MHz 1.
