L6000

SINGLE CHIP READ & WRITE CHANNEL

ADVANCE DATA

SUPPORTS 9-32Mbit/s DATA RATE OPERA-

TION IN RLL [1,7] CONSTRAINT

- Data Rate is Programmable

SUPPORTS ZONED BIT RECORDING AP-

PLICATIONS

LOW POWER OPERATION (500mW TYPI-

CAL @ 5V @ 32Mbits/Sec

PROVIDES PROGRAMMABILITY THROUGH

SERIAL MICROPROCESSOR INTERFACE

AND INTERNAL REGISTERS

- Bi-directional access to internal registers of

pulse detector, filter, servo demodulator,

frequency synthesizer and data separator.

PROGRAMMABLE POWER DOWN MODES

Full power-down mode (5mW max.)

POWER SUPPLY RANGE 4.3 to 5.5V

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

PIN CONNECTION

(Top view)

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.
