The divider/multiplier block is present (Divider/Multiplier: Yes/No), so the output frequency can be scaled relative to the input — but the multiplier path is not available (No), meaning only division is supported. For designs that require a multiplied clock (e.g., generating a higher-frequency core clock from a low-frequency crystal), this part will not work; a PLL with both divider and multiplier would be needed. ## Package and footprint The 20-TSSOP package (4.40 mm body width, 0.173\" pitch) is a standard fine-pitch surface-mount footprint. The supplier device package is also 20-TSSOP, so no second-level package marking discrepancy. The shipping medium is Bulk (not tape-and-reel), which is typical for engineering samples or low-volume production; for reel quantities, confirm the reel suffix with your distributor. ## Lifecycle and sourcing For dual-sourcing or a functional alternate, the CY2305SXI-1HT is a PLL-based clock generator in a similar role, but note the differences: the CY2305SXI-1HT offers 1:5 fanout (vs 1:2), operates from a single 3.0V supply, and is rated for -40°C to 85°C — a wider temperature range that may suit industrial environments the IMISM530ATB cannot cover.","metaTitle":"IMISM530ATB Spread Spectrum Clock Generator, PLL, 20-TSSOP","metaDescription":"IMISM530ATB spread spectrum clock generator with PLL, dual supply 3.135V–3.465V / 4.5V–5.5V, CMOS/TTL output, 20-TSSOP.
