9DB202CGLF

Overview

The Renesas 9DB202CGLF is a PCI Express jitter attenuator and multiplexer IC designed for PCIe applications. It features a single PLL circuit with a 1:2 input-to-output ratio, supporting differential inputs and outputs. The device operates within a supply voltage range of 3.135V to 3.465V and supports a maximum frequency of 140MHz. It accepts HCSL, LVDS, LVHSTL, LVPECL, and SSTL input signals, providing HCSL outputs. Packaged in a 20-TSSOP (4.40mm wide) surface-mount housing, it functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• PCIe Jitter Attenuation: Integrated PLL-based jitter reduction for PCI Express clocking architectures.
• Multiplexing Capability: Supports 1:2 input-to-output ratio with selectable input sources.
• Flexible Input Compatibility: Accepts multiple logic families including HCSL, LVDS, LVHSTL, LVPECL, and SSTL.
• Differential Signaling: Provides differential output signaling compliant with HCSL standards.

Applications

• PCI Express (PCIe) clock generation and distribution systems
• High-performance computing platforms requiring low-jitter clocking
• Server and networking equipment utilizing PCIe interfaces

Procurement Notes

Verify component status as the 9DB202CGLF is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure RoHS compliance documentation matches specific production batches. Check for alternative lead times due to end-of-life status. Validate package integrity upon receipt.

Selection Notes

Select this component when designing PCIe Gen 1-3 systems requiring jitter attenuation and input multiplexing. Ensure the design accommodates the 20-TSSOP package dimensions and 0°C to 70°C industrial temperature range. Verify that input signal levels match supported formats (HCSL, LVDS, etc.). Consider power supply constraints within the 3.135V to 3.465V range during PCB layout.

Part Context

The 9DB202CGLF belongs to the Renesas 9DB202 family of PCIe clock generators and jitter attenuators. It serves as a specialized timing solution for maintaining signal integrity in high-speed serial interfaces. The 'GLF' suffix typically denotes the tape-and-reel packaging variant and RoHS-compliant material composition within the broader product line.

Replacement Considerations

RC19013A100GNG#KB0 is identified as a manufacturer-recommended replacement for the 9DB1200 series; however, direct substitution for the 9DB202CGLF requires verification of pin compatibility and functional equivalence against current inventory options.
