Clock generators can replace multiple crystals or oscillators
Delivering low power and low jitter scalability, the VersaClock 3S devices meet requirements for widely used standards including PCI Express® Gen 1/2/3 and are ideal for consumer, industrial, computing and automotive applications.
The 5P35023 and 5P35021 chips deliver a unique set of features offering an optimal combination of performance, power and flexibility. These features include:
Proactive Power Saving — the first intelligent timing device to detect power down status of the downstream clocked component, resulting in further energy savings in the system;
Performance-Power Balancing — a user-friendly interface allowing users to easily minimize power consumption based on targeted performance;
Dynamic Frequency Control — supported by one-time programmable (OTP) memory, this feature provides the system the ability to dynamically switch between up to four programmed frequencies, allowing optimized performance and power consumption;
Overshoot Reduction Technology — prevents unwanted frequency overshoot that can lead to system failures during fast frequency changes.
The devices have an extremely low-power digitally controlled oscillator supplying the system with a 32.768 kHz clock that can be powered by a coin battery, making it ideal for handheld and battery-powered applications.
The VersaClock 3S 5P35023 has three single-ended LVCMOS outputs and two differential outputs that support LVPECL, LVDS, LP-HCSL, and single-ended LVCMOS. The 5P35021 has one single-ended LVCMOS output and two differential outputs. Both versions feature a low-power 32.768 kHz clock output with less than 2 μA current consumption for use as a system RTC reference clock.
The 5P35023 is available in a 4 x 4 mm 24-QFN package, and the 5P35021 is available in a 3 x 3 mm 20-QFN package.
