It takes a single differential clock input and regenerates four HCSL (High-Speed Current Steering Logic) outputs with deterministic, low-skew timing — the zero-delay characteristic means the output edges align to the input within the PLL's tracking bandwidth, eliminating the propagation delay you would see from a simple fanout buffer. The 1:4 fanout ratio and 166 MHz maximum frequency cover PCIe Gen1 and Gen2 reference clock requirements. The differential input and output suit it for routing over long traces on a server motherboard or add-in card where common-mode noise rejection matters. ## Sourcing and lifecycle — active, no LTB concern The 9DB433AGLF carries an Active product status and is listed as current lifecycle stage. For BOM-freeze planning, this part is safe for new designs and ongoing production through independent distribution. ROHS3 compliant, so it meets the latest EU restriction requirements without an exemption expiry.","metaTitle":"9DB433AGLF PCIe Zero-Delay Clock Buffer, 166 MHz, 28-TSSOP","metaDescription":"9DB433AGLF PCI Express zero-delay clock buffer with PLL, 1:4 HCSL outputs, 166 MHz max, 3.3V supply, 28-TSSOP.

Electrically and functionally they are identical."},{"question":"Does 9DB433AGLF support PCI Express Gen3?","answer":"The 9DB433AGLF is specified for PCI Express (PCIe) as its main purpose and runs at 166 MHz max, which covers the 100 MHz reference clock used by Gen3. However, Gen3 also requires tighter output jitter (typically < 1 ps RMS); verify the datasheet's jitter specification against your Gen3 controller's requirements before committing the BOM."},{"question":"What is a zero delay buffer?","answer":"A zero delay buffer uses a PLL to align its output clock edges to the input reference, effectively cancelling the propagation delay through the device. The 9DB433AGLF does this for PCIe clock distribution, ensuring that downstream devices see the same timing as the source."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/9DB433AGLF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/9DB433AGLF when reusing this data.
