CS2100CP-EZZR

Clock Generators, PLLs, Frequency Synthesizers Overview

The CS2100CP-EZZR is a fractional-N clock multiplier and jitter reduction IC from the Cirrus Logic CS2000 series. It utilizes a hybrid analog-digital PLL architecture to generate a low-jitter 6 MHz to 75 MHz output clock from noisy or intermittent reference sources ranging from 50 Hz to 30 MHz. The device supports I²C and SPI control ports for full software configuration. It operates on a 3.1 V to 3.5 V supply with a typical current consumption of 12 mA. The component is housed in a 10-pin MSOP package and is rated for an extended operating temperature range of -40°C to +105°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates low-jitter clocks (6-75 MHz) from noisy inputs (50 Hz-30 MHz)
• High accuracy with less than 1 PPM error in high-resolution mode
• Hybrid analog-digital PLL eliminates need for external loop filter components
• Supports both I²C and SPI™ control interfaces

Clock Generators, PLLs, Frequency Synthesizers Applications

• Timing reference clock generation for system microcontrollers
• Jitter reduction for audio and video synchronization
• Clock multiplication for wireless communication systems

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'EZZR' against the manufacturer's ordering guide to confirm the Automotive-E grade (-40°C to +105°C) and tape-and-reel packaging. Confirm RoHS compliance status as per the latest datasheet revision. Check for obsolescence notices, as the CS2100 family has been subject to discontinuation notifications.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part when an extended industrial or automotive temperature range is required. Ensure the input reference frequency falls within the 50 Hz to 30 MHz limit. Verify that the desired output ratio can be achieved within the device's synthesis resolution limits. Consider the 10-MSOP package constraints for PCB layout.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the CS2100-CP family of fractional-N synthesizers. The 'E' suffix typically denotes the Automotive-E temperature grade (-40°C to +105°C), distinguishing it from Commercial (-10°C to +70°C) or Automotive-D grades. The 'ZR' suffix indicates the reel packaging format.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the CS2100-CP family (e.g., CS2100CP-CZZR) if temperature range requirements differ.
