Product Summary
The CY2273APVC-1 is a clock synthesizer/driver for a Pentium, Pentium II, Cyrix, or AMD processor-based PC using Intels 82430TX, 82440LX, ALI Aladdin IV or Aladdin IV+ chipsets. The CY2273APVC-1 outputs are designed for low EMI emissions. Controlled rise and fall times, unique output driver circuits and factory-EPROM programmable output drive and slew-rate enable optimal configurations for EMI control.
