CXA3010Q Overview
Key Specifications
Package: QFP
Operating Voltage: 5 V
Max Voltage (typical range): 6 V
Min Voltage (typical range): 4.4 V
Description
The CXA3010Q 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 preamplifier input conversion noise voltage of 2.0nV/√ Hz (typ.) keeps read data output jitter to a minimum - Preamplifier voltage gain can be switched between 39dB and 45dB - In inner track mode (OTF = Low), the voltage gain is boosted by 3dB, making it possible to minimize peak shift in inner tracks.
