Supply voltage is tight at 3.15V to 3.45V, so the 3.3V rail must be clean and within ±4.5% — a standard 3.3V ±5% supply is marginal without post-regulation. ## Package and footprint considerations Supplied in Tube (the #PBF suffix denotes lead-free, ROHS3-compliant finish). For reel quantities, order the LTC6957IDD-1#TRPBF variant. ## Lifecycle and supply posture Sourced to order against your BOM quantity; confirm lead time and pricing via RFQ.","metaTitle":"LTC6957IDD-1#PBF Clock Fanout Buffer 300 MHz LVPECL 12-DFN","metaDescription":"LTC6957IDD-1#PBF Analog Devices fanout buffer, 300 MHz, LVPECL output, 1:2 ratio, 3.15-3.45V supply, -40°C to 85°C, 12-DFN.
