27 MHz video clock generator in an 8-pin SOIC
The Cypress CY2410KSXC-5 is a fixed-frequency clock generator built around an integrated PLL, producing a single 27 MHz clock output from a clock input. Its description as a video clock generator tells you this part was designed for display timing — think VGA controllers, LCD panels, or video encoder/decoder reference clocks where 27 MHz is the standard pixel clock rate. The 1:1 input-to-output ratio means it's a clean clock conditioner — it takes a reference clock in and delivers a jitter-cleaned, PLL-multiplied 27 MHz out. There's no divider or multiplier on the output side, so the output frequency is fixed at the PLL's locked frequency. Packaged in an 8-SOIC with surface-mount termination, it fits a standard SOIC-8 footprint — easy to hand-solder or rework with a basic hot-air station. The commercial temperature range of 0°C to 70°C limits it to indoor, temperature-controlled gear; don't spec this for an engine bay or rooftop radio.
Supply rail and PLL lock considerations
Because the input is a clock, not a crystal, you need an external oscillator or another clock source driving the input pin. There's no on-chip crystal oscillator — the PLL locks to whatever clock you feed it. If your design has a 27 MHz crystal and you expected this to replace a crystal oscillator, you'll need a different part or an external oscillator can.
Active lifecycle — no obsolescence headache
The CY2410KSXC-5 carries an active lifecycle status and is ROHS3 compliant. No last-time-buy deadlines to chase, no premium for NOS (new old stock). For a BOM line that needs a fixed 27 MHz clock generator in SOIC-8, this is a straightforward, current-production choice.
