Description

The 5P35021-152 is the latest VersaClock programmable clock

generator and is designed for low-power, consumer, automotive,

and high-performance PCI Express applications. The 5P35021

device is a 3 PLLs architecture design; each PLL is individually

programmable and allows up to 3 unique frequency outputs.

The 5P35021-152 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. After power up, the user can change

the device register settings through the I2

C interface when I2C

mode is selected. It also has programmable VCO and PLL source

selection to allow the user to do power-performance optimization

based on the application requirements.

The device provides one single-ended output and two pairs of

LP-HCSL differential outputs.
