128 MHz spread-spectrum clock generator in an 8-TSSOP
The Cypress CY25814ZC is a PLL-based clock generator that integrates a frequency modulator and spread-spectrum clock generator in a single 8-TSSOP package. It accepts a clock, crystal, or resonator input and delivers a single clock output up to 128 MHz, with an internal divider and multiplier for flexible frequency synthesis. The spread-spectrum modulation reduces peak EMI emissions on the output clock, which can save board space by minimizing the need for external ferrite beads or shielding cans on the clock trace.
Supply range and temperature grade — commercial only
The CY25814ZC operates from a 2.97 V to 3.63 V supply. The temperature range is 0°C to 70°C.
RoHS non-compliant — plan your solder process
The CY25814ZC is listed as RoHS non-compliant. That means the device uses leaded solder (typically tin-lead) on the terminations. If your assembly line is RoHS-only (lead-free reflow profile), this part will not wet properly and risks tombstoning or poor solder joints. You will need either a leaded reflow step or a waiver.
Package and mounting — 8-TSSOP, surface-mount
Housed in an 8-lead TSSOP with 4.40 mm body width, the CY25814ZC is a surface-mount device.
