5L35023

The 5L35023 is a VersaClock^® programmable clock generator designed for low-power, consumer, and high-performance PCI Express applications. The 5L35023 device is a three-PLL architecture design, and each PLL is individually programmable and allows for up to five unique frequency outputs.

The 5L35023 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 without programming after power up, and then program the 5L35023 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 three single-ended outputs and two pairs of differential outputs that support LVCMOS and LPHCSL. A low-power 32.768kHz clock is supported with less than 2μA current consumption for the system RTC reference clock.
