What this clock generator does on your board
The Cypress CY26200SC is a single-channel PLL-based clock generator in an 8-SOIC package. It takes a crystal input and delivers a clean clock output at one of two selectable frequencies: 1.544 MHz or 2.08 MHz.
1.544 MHz and 2.08 MHz — what the output frequencies mean
The two output frequencies map to legacy telecom and T1/ framing rates. 1.544 MHz is the T1 line rate in North America; 2.048 MHz is the line rate used in Europe and much of the rest of the world. If your board generates or regenerates those clock domains for a framer, line interface, or backplane timing, the CY26200SC covers both with a single crystal and a logic-level select pin. The output is single-ended CMOS, not differential — the differential input and output are both marked No, so this part drives a single trace, not a twisted pair. That is fine for on-board clock distribution up to a few inches; for longer runs or noisy environments you would buffer it.
Package and mounting
The CY26200SC comes in an 8-pin SOIC with a 3.90 mm body width (the 0.154 inch variant). It is surface-mount, so it reflows with the rest of the board. The supplier device package is listed as 8-SOIC, which is the standard narrow-body footprint.
Lifecycle and sourcing
That means no LTB risk and no forced redesign for the foreseeable future. If you are freezing a BOM for a production run, this part is a stable line item.
