RENESAS 9FGL6241AQ202LTGI

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.

• Automatically detects presence or absence of input clocks
• Integrated terminations on LP-HCSL 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 to 3.3V operating voltage (VDDREF is 1.8V)
• 4 × 4 mm 28-VQFP-N package with external crystal
• 4 × 4 mm 28-LGA package with optional internal crystal

• 1 × 4 and 2 × 2 nVME SSDs
• 3:2 PCIe clock multiplexing
