Clock for Intel® Chipsets

The NCT1063Y-585 is a Clock Synthesizer for Intel Calpella platform which compliant with the Intel CK505 specification. The NCT1063Y-585 provides most of the clocks required for a high-speed microprocessor and integrates the regulator and series terminated resistors.

The NCT1063Y-585 provides SMbus serial bus interface to program the registers to enable or disable each clock output and provides -0.5% down type spread spectrum or programmable S.S.T. scale to reduce EMI.

The NCT1063Y-585 accepts a 14.318 MHz reference crystal as its input and runs on single 3.3V supply.
