SGS THOMSON L6000 Single Chip Read & Write Channel for 9-32Mbit/s Data Rate

Category: Electronics, Interface ICS, STMicroelectronics Inc

Overview of the L6000 Chip

The L6000 by SGS THOMSON MICROELECTRONICS is a single-chip solution designed to handle both reading and writing tasks for data rates ranging from 9 to 32 Mbit/s. This advanced data device is suitable for Run Length Limited (RLL) constraint operations at a programmable data rate and offers compatibility with Zoned Bit Recording applications.

Key Features

The L6000 chip operates efficiently with low power consumption, typically requiring 500mW at 5V for a 32Mbits/sec data rate. Programmability is a core feature, with the device providing a serial microprocessor interface and internal registers for customized settings. It operates within a temperature range of 0°C to 70°C.

Bidirectional access to internal registers allows for the efficient management of various components, including the pulse detector, filter, servo demodulator, programmable active filter, servo frequency synthesizer, and data separator. The device supports programmable power down modes for energy conservation, with a full power-down mode drawing a maximum of 5mW.

Operation and Flexibility

Functionality is set via a single external resistor that determines the reference current for the internal DAC and thus the data rate. With the versatility to switch between zones in zoned bit recording applications without changing external components, the L6000 provides additional flexibility for users.

Built with advanced BiCMOS technology, the L6000 integrates all functions required to implement a high-performance read channel. This includes various demodulators, synthesizers, filters, and separators, ensuring reliable and efficient data processing.

Power Supply and Pin Configuration

The device is powered by a supply voltage in the range of 4.3 to 5.5V. The pin configuration, presented from a top view, includes several connections such as Level, Clock, Data, Write Clock, Multiplex Taps, Ground, and more, providing a comprehensive set of interfaces for communication and control.
