Overview
L6000 SINGLE CHIP READ & WRITE CHANNEL ADVANCE DATA SUPPORTS 9-32Mbit/s DATA RATE OPERATION IN RLL [1,7] CONSTRAINT - Data Rate is Programmable SUPPORTS ZONED BIT RECORDING APPLICATIONS LOW POWER OPERATION (500mW TYPICAL @ 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 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.
