1821-4600 - Brand New Texas Instruments IC Chips
-
Description
The Electronic Component Model 1821-4600 is a versatile spread spectrum frequency modulator designed specifically for a wide range of input clock frequencies from 10 to 160 MHz. It can generate an EMI reduced clock from crystal, ceramic resonator, or system clock. The model offers various combinations of spread options and percentage deviations, including Down Spread, Center Spread, and a percentage deviation range from ±0.625% to -3.50%.
Specifications and features
• FCC approved method of EMI attenuation
• Provides up to 15 dB EMI reduction
