SZA1000 - NXP

SZA1000 QIC digital equalizer

The SZA1000 is a single chip digital equalizer for single channel QIC (Quarter Inch Cartridge) systems with MR (Magneto Resistive) heads. It can be used with QIC 3010, QIC 3020, QIC 3080, QIC 3095, Travan 2, 3, 4 and 5, and similar formats. It replaces a pulse detector, programmable filter and data synchronizer, and adds a FIR filter to the conventional anal.

Features

• 3-wire serial interface for programming and status reading
• Suitable for MFM (Modified Frequency Modulation), RLL 1,7 (Run Length Limited) and similar codes
• Transfer rates with MFM code from 250 kbits/s to 4 Mbits/s
• Transfer rates with RLL(1,7) code from 500 kbits/s to 12 Mbits/s
• Programmable FIR (Finite Impulse-Response) filter makes it possible to equalize complex and asymmetric channel impulse responses
• Programmable fixed and tracking qualification thresholds provide reliable data recovery in read mode, and reliable bad sector detection in verify mode
• Read pulse output for flop.
