Description

The 5L35021 is a member of the VersaClock 3S programmable clock generator family with 1.8V operation voltage, and is designed for industrial, consumer, and PCI Express applications. The device features a 3 PLL architecture design; each PLL is individually programmable and allowing up to 6 unique frequency outputs.

The 5L35021 has built-in 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, then program the 5L35021 again through the I2C interface.

Features

▪ 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 based on required performance

▪ DFC: Dynamic Frequency Control feature allows user to dynamically switch between and up to 4 different frequencies smoothly

▪ Spread spectrum clock to lower system EMI

▪ I2C interface

▪ Suspend Mode, featuring RTC clock only when system goes into low-power operation modes
