4-PLL High Performance Clock Generator

Cypress’s CY274X is a 4-PLL High-Performance Clock Generator.

In the recent times consumer devices have become feature-rich and connected. Sharing high-resolution media content requires faster data transfer standards. Consumer devices must support multiple data standards, each with specific timing requirements. What this essentially means is – consumer devices require highly integrated and flexible timing solutions. And this is precisely why we have designed the CY274X High Performance Clock Generator.

Best-In-Class

The 4-PLL (Phase Locked Loop) High Performance Clock Generator can generate up to 12 outputs, where eight outputs can be configured as differential or single-ended, and the remaining four are dedicated single-ended outputs. With support for frequencies up to 700 MHz and RMS Phase jitter of less than 0.7ps, CY274X can support reference clocks for PCIe1.0/2.0/3.0, SATA1.0/2.0/3.0, 10GbE and USB 1.0/2.0/3.0 peripherals.

Additional Benefits

The High Performance Clock Generator offers Frequency Select feature, glitch-free frequency switching, and can also be configured as zero or non-zero delay buffer. It provides VCXO functionality and a cascading PLL option to generate critical frequencies with a fixed reference. It reduces EMI (Electro-Magnetic Interference) using Spread Spectrum Modulation, and has an RTC (Real Time Clock) to offer. The High Performance Clock Generator also has an AEC-Q100 qualified automotive variant.

Great Applications

The 4-PLL High Performance Clock Generator has a wide range applications. Applications in Multi-Function Printers, Car Infotainment Systems, Media Broadcast Systems, Routers & Switches, Femtocells, and many more options.
