Product details

The Cypress CY2SSTV857ZC-27T is a PLL-based zero delay buffer in the SSTV series, designed to regenerate and distribute a reference clock with near-zero propagation delay between input and output. It accepts a differential clock input and delivers ten differential clock outputs, all running at up to 200 MHz. The 1:10 fanout ratio means a single device can feed ten DDR memory or logic loads without needing a second buffer stage, which simplifies the clock tree on a memory-intensive board.

The supply range is 2.38 V to 2.63 V. The differential input and output paths (Yes/Yes per the spec) mean this part is meant for LVDS or HCSL-style signaling, not single-ended CMOS clocks.

Listed as Active in production status.

Frequently asked questions

What are the alternatives to CY2SSTV857ZC-27T?

Within the same SSTV series, the pin-compatible density options share the same 48-TFSOP footprint and 1:10 fanout architecture. The -27T speed grade indicates 200 MHz operation; other speed grades in the family offer different maximum frequencies while maintaining the same pinout and supply voltage.

What is CY2SSTV857ZC-27T's listed type?

It is a Zero Delay Buffer — a PLL-based clock driver that aligns the output phase to the input with near-zero propagation delay, used for distributing a clean reference clock across multiple loads.
