9FGL6241 Overview
The 9FGL6241 / 9FGL6251 are intelligent buffer/clock generators tailored for single and dual-ported nVME SSDs. They support mon (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.
9FGL6241 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
- 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)
