Overview
The Atmel ATR0849-PFQG is a laser diode driver designed for high-speed optical recording applications, specifically supporting 8x write speeds for Dual Layer DVD media. This component belongs to the Low Voltage Differential Signals (LVDS) laser diode driver series, which expands Atmel's portfolio for higher performance writing requirements. The device integrates necessary control logic and drive circuits to manage laser diode operations efficiently within optical disc drives.
Feature Summary
- Supports 8x write speed capabilities for Dual Layer DVD formats
- Utilizes Low Voltage Differential Signals (LVDS) technology for signal integrity
- Part of an expanded series for higher speed optical writing applications
Applications
- Dual Layer DVD writers
- Optical disc drive systems requiring high-speed writing
- Laser diode control modules in optical storage devices
Procurement Notes
Verify the specific suffix PFQG against official Microchip or Atmel documentation to confirm package type and temperature range. Ensure compatibility with existing LVDS interface designs. Confirm supply status as legacy components may have limited availability or be subject to last-time buy notices from the manufacturer.
Selection Notes
Select this component when designing for 8x Dual Layer DVD writing speeds. It is suitable for systems requiring LVDS-based laser control. Consider pinout compatibility and thermal management requirements associated with the PFQG package. Evaluate power consumption characteristics relative to system constraints.
Part Context
Atmel was acquired by Microchip Technology in 2016. Products formerly branded under Atmel are now managed under the Microchip portfolio. The ATR0849 series represents legacy optical drive components that remain relevant for maintenance and specific high-speed optical recording implementations.
Replacement Considerations
Check for direct substitutes within the ATR0839/ATR0849 family. Verify if newer Microchip optical drivers offer backward compatibility. Consult official substitution guides for package and electrical equivalence.
