5X35023 Datasheet | Renesas

Versa Clock® Programmable Clock Generator 5X35023 Datasheet Description The 5X35023 is the latest Versa Clock programmable clock generator with an integrated crystal, and is designed for low power, consumer, and high-performance PCI Express applications. The 5X35023 device is a 3 PLL architecture design, and each PLL is individually programmable allowing for up to 6 unique frequencies outputs. The device 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, user can change the register setting through the I2C interface when I2C mode is selected. The device has programmable VCO and PLL source selection to allow power-performance optimization base on the application requirements. The device supports 3 single-ended outputs and two pairs of differential outputs that support LVCMOS, LVPECL, LVDS and LP-HCSL. Low Power 32.768k Hz clock is supported with only less than 2μA current consumption for system RTC reference clock. Typical Applications - PCIe Gen1/2/3 clock generator - Consumer application crystal replacements - Smart Device, Handheld, puting and Consumer applications 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 base on required performance - DFC: Dynamic Frequency Control feature allows up to 4 difference frequencies to switch dynamically - Spread spectrum clock support to lower system EMI - I2C interface - Integrated 25MHz crystal Key Specifications - PCIe clocks phase jitter: PCIe Gen3 - Differential clocks < 3 ps rms jitter integer range 12k Hz- 20MHz Output Features - 2 DIFF outputs with configurable...
