9DB1200CGLF-SUN

Overview

The 9DB1200CGLF is a PCI Express clock buffer and driver manufactured by Renesas Electronics Corporation. It features an integrated Phase-Locked Loop (PLL) to generate twelve differential HCSL outputs from a single differential input, providing a 1:12 fanout ratio. The device operates at frequencies up to 400MHz with a supply voltage range of 3.135V to 3.465V. Packaged in a 64-TFSOP (TSSOP) housing, it is designed for high-speed timing applications within the PCIe ecosystem. The component supports surface-mount installation and functions within a commercial temperature range of 0°C to 70°C.

Procurement Notes

The manufacturer lists this part number as End-of-Life (EOL). Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Buyers should confirm RoHS3 compliance status and review Product Change Notices (PCN) regarding assembly site changes or label modifications issued prior to discontinuation.

Selection Notes

Select this component when a single differential clock source must drive up to twelve PCIe endpoints using HCSL signaling. Ensure the design accommodates the 3.3V nominal supply voltage and the 64-pin TSSOP footprint. Verify that the required operating frequency does not exceed 400MHz and that the commercial temperature range meets the system environmental requirements.

Part Context

This device belongs to the 9DB1200 family of PCIe timing solutions. It serves as a fanout buffer to reduce jitter and distribute reference clocks across multiple slots. The suffix 'GLFT' typically denotes lead-free packaging and tape-and-reel shipping configuration, while 'C' indicates the commercial temperature grade.

Replacement Considerations

Renesas recommends the RC19013A100GNG#KB0 as a manufacturer-recommended replacement. Users should verify pin compatibility and electrical specifications before substitution.
