The internal PLL can be bypassed, letting the part act as a simple fanout buffer when you don't need the phase alignment. Maximum output frequency is 133 MHz, which covers most PCI, Ethernet, and general-purpose logic clock domains. The 1:5 ratio means one clock source drives up to five loads without external fanout trees or additional buffers. ## Package and footprint Housed in an 8-pin SOIC (0.154\" body width, 3.90 mm), surface-mount. The supplier device package is 8-SOIC. Standard SOIC-8 land pattern; no surprises for the PCB layout. Ships in tube — if your pick-and-place expects tape, verify the reel option with your distributor. ## Lifecycle and sourcing reality The 2305B-1DCG carries an Active product status and is ROHS3 compliant.","metaTitle":"2305B-1DCG Zero Delay Buffer, 133 MHz, 8-SOIC, Active","metaDescription":"2305B-1DCG zero delay buffer from Renesas.

The 2305B-1DCG includes a PLL that can be bypassed, allowing it to function as a simple fanout buffer when phase alignment is not needed."},{"question":"How does a zero delay buffer differ from a PLL?","answer":"A PLL is a general-purpose frequency synthesis and phase-locking circuit. A zero delay buffer is a specific application of a PLL — it takes one input clock and produces multiple output clocks that are phase-aligned (zero delay) with the input. The 2305B-1DCG integrates a PLL that can be bypassed, so it can serve either role."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/2305B-1DCG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/2305B-1DCG when reusing this data.
