VersaClock 3S Programmable Clock Generator with Integrated Crystal

The 5X35023 VersaClock® programmable clock generator is designed for low-power, consumer, and high-performance PCI Express applications. The device is a three-PLL architecture design, and each PLL is individually programmable and allows for up to five unique frequency outputs.

The 5X35023 has built-in unique features such as Proactive Power Saving (PPS), Performance-Power Balancing (PPB), Overshoot Reduction Technology (ORT), and Extreme Low Power DCO. An internal OTP memory allows the user to store the configuration in the device without programming after power up, then program the 5X35023 again through the I²C interface.

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 one single-ended output and two pairs of differential outputs that support LVCMOS, LP-HCSL, LVDS, and LVPECL. A low-power 32.768kHz clock is supported with only less than 2μA current consumption for a system RTC reference clock.
