NCT1063Y-585

Overview

The NCT1063Y-585 is a clock synthesizer designed for the Intel Calpella platform, compliant with the Intel CK505 specification. It generates high-speed microprocessor clocks using a single 3.3V supply and a 14.318 MHz reference crystal input. The device integrates an onboard regulator and series terminated resistors. Key electrical parameters include a maximum output frequency of 14.318 MHz for specific outputs and operation at 3.3V. It features programmable spread spectrum capabilities to reduce EMI and provides multiple differential and single-ended clock outputs via a 32-WFQFN package.

Feature Summary

• Provides 2 pairs of push-pull differential CPU clocks, 1 pair for DOT_96, and selectable SRC/SATA or SRC differential outputs.
• Integrates a voltage regulator and series terminated resistors within the IC.
• Supports -0.5% down-type spread spectrum and programmable SST scale for EMI reduction.
• Features amplitude controllable differential clocks and programmable slew rate control.

Applications

• Intel Calpella platform systems
• High-speed microprocessor clock generation
• SATA and SRC clock distribution

Procurement Notes
