9DB1200CGLFT-INT

Overview

The Renesas Electronics Corporation 9DB1200CGLFT is a PCI Express (PCIe) clock buffer and driver IC featuring an integrated Phase-Locked Loop (PLL). It accepts a single differential input and provides twelve differential HCSL outputs, operating at frequencies up to 400MHz. The device functions within a supply voltage range of 3.135V to 3.465V and is housed in a 64-TFSOP package with a width of 6.10mm. Designed for PCIe applications, it supports the industrial temperature range of 0°C to 70°C.

Feature Summary

• Integrates a PLL for jitter attenuation and clock generation
• Converts differential input to twelve differential HCSL outputs
• Supports maximum operating frequency of 400MHz
• Designed specifically for PCI Express (PCIe) timing solutions

Applications

• PCI Express (PCIe) system clock distribution
• High-speed data acquisition systems requiring precise timing
• Telecommunications equipment clocking

Procurement Notes

The manufacturer lists this component as End-of-Life (EOL), with a discontinuation notice dated March 24, 2022. Verification of current stock availability through authorized distributors is required. Buyers should confirm RoHS3 compliance status and check for any pending Product Change Notices regarding assembly sites or labeling updates before procurement.

Selection Notes

Select this component when a high-fanout PCIe clock buffer with integrated PLL is required. Ensure the design accommodates the 64-pin TSSOP footprint and the specific 3.135V to 3.465V power supply rails. Verify that the 400MHz maximum frequency meets the target bus speed requirements and that the HCSL output swing is compatible with downstream receiver inputs.

Part Context

This part belongs to the 9DB1200 family of PCIe clock buffers. It serves as a specialized timing solution for generating multiple low-jitter clock signals from a single reference source. The 'GLFT' suffix indicates the lead-free tape-and-reel packaging format used by the manufacturer.

Replacement Considerations

Renesas recommends the RC19013A100GNG#KB0 as a replacement for this discontinued product. Engineers should evaluate the pinout compatibility and electrical specifications of the recommended substitute against the original design requirements.
