VersaClock 3S Programmable Clock Generator

The 5P35023 is a VersaClock programmable clock generator and is designed for low power, consumer, and high-performance PCI Express applications. The 5P35023 device is a three PLL architecture design, and each PLL is individually programmable and allowing for up to six unique frequency outputs. The 5P35023 has built-in unique features such as Proactive Power Saving (PPS), Performance-Power Balancing (PPB), Overshot Reduction Technology (ORT) and Extreme Low Power DCO. An internal OTP memory allows the user to store the configuration in the device. After power up, the user can change the device register settings through the I²C interface when I²C mode is selected. The device has programmable VCO and PLL source selection to allow the user to do power-performance optimization based on the application requirements. It also supports three single-ended outputs and two pair of differential outputs that support LVCMOS, LVPECL, LVDS and LPHCSL. A Low Power 32.768kHz clock is supported with only less than 2µA current consumption for system RTC reference clock.

• Configurable OE pin function as OE, PD#, PPS or DFC control function
• Configurable PLL bandwidth/minimizes jitter peaking
• PPS: Proactive Power Saving features save power during the end device power down mode
• PPB: Performance- Power Balancing feature allows minimum power consumption base on required performance
• DFC: Dynamic Frequency Control feature allows user to dynamically switch between and up to 4 difference frequencies smoothly
• Two PLLs support independent Spread Spectrum clocks to lower system EMI
• Store user configuration into OTP memory
• I²C interface
