Maximum operating frequency of 133 MHz covers common bus clocks for DDR, PCI, and Ethernet MAC interfaces, though the non-differential I/O means it is suited for single-ended clock trees rather than differential pairs like LVDS or HCSL. The PLL bypass mode lets the input clock pass directly to the outputs without phase alignment — useful for test, low-frequency operation where PLL lock time is unacceptable, or when the reference clock is already jitter-compliant and only fanout is needed. ## Supply rail and temperature grade The 1:9 fanout ratio with no internal divider or multiplier means the output frequency equals the input frequency — the part does not synthesize higher or lower clocks, it only buffers and phase-aligns. ## Package and board integration Housed in a 16-SOIC package with 3.90 mm body width, the footprint matches industry-standard SOIC-16 land patterns. Surface-mount assembly with a 1.27 mm pitch is straightforward for standard reflow profiles and does not require via-in-pad or microvia fanout. No official second-source or pin-compatible cross-reference is recorded in the manufacturer's documentation. The closest parametric peer is the 23S05-1DCG, which offers a 1:5 fanout ratio instead of 1:9 — the package and supply voltage differ, so a board spin would be required for substitution.","metaTitle":"Renesas 23S09T-1DCG Zero Delay Buffer, 133 MHz, 16-SOIC","metaDescription":"Renesas 23S09T-1DCG Zero Delay Buffer with PLL bypass, 133 MHz max, 1:9 fanout, LVTTL I/O, 2.3-2.7V supply, 16-SOIC.
