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
TQFP64
(10 x 10)
ORDERING NUMBER: L6000
OPERATING TEMPERATURE: 0°C to 70°C
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 compat-
ible with zoned bit recording applications. Exter-
nal components do not need to be changed when
switching between zones. The L6000 is manufac-
tured using an advanced BiCMOS technology.
