CXA3031Q - Read/Write Amplifier (with Built-in Filters) for FDDs

Datasheet Summary

Description

The CXA3031Q is a monolithic IC designed for use with three-mode Floppy Disk Drives, and contains a read circuit (with a four-mode filter system), a write circuit, an erase circuit, and a supply voltage detection circuit, all on a single chip.

Features

  • Single 5V power supply.
  • Filter system can be switched among four modes: 1M, 1.6M/2M, which are each inner track/outer track.
  • Filter characteristics can be set to Chebyshev (1dB ripple) for 1.6M, 2M/inner track only, and to Butterworth for the other modes.
  • A custom selection can be made between Chebyshev (1dB ripple) and Butterworth for the filter characteristics for 1.6M, 2M/inner track only.
  • Permits customization of the fc ratio.
  • Low preamp.
