DESCRIPTION

The L6000 is a 5V single chip read channel IC. It contains all the functions needed to implement a high performance read channel including the pulse detector, programmable active filter, servo demodulator, frequency sinthesizer, and data separator, at data rates up to 32 Mbit/s. A single external resistor sets the reference current for the internal DAC which, in turn, fixes the data rate.

This device is programmed through a serial port and banks of internal registers. It is fully compatible with zoned bit recording applications. External components do not need to be changed when switching between zones. The L6000 is manufactured using an advanced BiCMOS technology.
