9DB1200CGLFT

Overview

The 9DB1200CGLFT is a PCI Express clock buffer and driver manufactured by Renesas Electronics Corporation. It features a single input to twelve output configuration with a maximum frequency of 400MHz. The device operates on a supply voltage ranging from 3.135V to 3.465V and supports both differential input and output signals. It utilizes HCSL output logic and includes an integrated PLL for jitter attenuation. The component is housed in a 64-TFSOP package, measuring 6.10mm in width, and is designed for surface mount installation within an operating temperature range of 0°C to 70°C.

Feature Summary

• PCI Express clock buffer/driver with 1:12 input-to-output ratio
• Maximum operating frequency of 400MHz with integrated PLL
• Differential input and output support using HCSL logic levels
• Available in a 64-TFSOP (TSSOP) surface-mount package

Applications

• PCI Express clock distribution networks
• High-speed digital system timing solutions
• Server and storage infrastructure clocking

Procurement Notes

Verify the current lifecycle status as the component is listed as discontinued. Confirm availability through authorized distributors or surplus channels. Ensure compliance with RoHS3 specifications and check for specific packaging options such as tape and reel or cut tape. Validate that the 64-TFSOP footprint matches the target PCB design requirements before procurement.

Selection Notes

Select this component when a 1:12 fan-out solution is required for PCIe applications up to 400MHz. Ensure the design accommodates the 3.135V to 3.465V supply voltage range. Verify that the HCSL output compatibility aligns with downstream receiver inputs. Consider the 64-pin TSSOP package constraints for thermal management and board space allocation during the schematic capture phase.

Part Context

This part belongs to the 9DB1200 series of clock buffers. It serves as a specialized timing solution for high-speed serial interfaces like PCI Express. The device integrates buffering and multiplexing capabilities to maintain signal integrity across multiple loads. It is distinct from other series members by its specific 1:12 output count and 400MHz frequency capability.

Replacement Considerations

Renesas recommends RC19013A100GNG#KB0 as a manufacturer-recommended alternative. Verify pinout compatibility and electrical parameter alignment before substitution.
