Description
The 5L35023 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 5L35023 has built-in 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
5L35023 again through the I2
C interface.
The device has programmable VCO and PLL source selection,
allowing power-performance optimization based on the application
requirements.

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

Typical Applications
▪ Embedded computing devices
▪ Consumer application crystal oscillator replacements
▪ SmartDevice, Handheld, and Consumer applications
