DS90CR486VS/NOPB

Overview

The DS90CR486VS/NOPB is a 133 MHz, 48-bit Channel Link deserializer manufactured by Texas Instruments. It converts high-speed serial data streams into parallel LVDS outputs for display applications. The device operates with a single 3.3 V supply and supports data rates up to 6.384 Gbps. It features an integrated PLL for clock recovery and includes configuration registers accessible via an I2C interface. The component is housed in a 72-pin VSOP package and is rated for operation within the -40°C to +85°C industrial temperature range.

Feature Summary

• Supports 48-bit parallel output through Low Voltage Differential Signaling (LVDS) interfaces
• Integrates a phase-locked loop (PLL) for robust clock recovery from the serial data stream
• Provides system configuration and status monitoring via a standard I2C bus interface

Applications

• Flat panel display systems requiring high-bandwidth video transmission
• Industrial control panels with large graphical user interfaces
• Medical imaging displays needing reliable high-resolution signal integrity

Procurement Notes

Verify the specific suffix VSOP against the required footprint dimensions on the target PCB. Confirm that the I2C address settings align with the system controller configuration. Ensure the design accounts for the thermal characteristics of the 72-pin package under maximum operating conditions. Cross-reference the datasheet revision date to confirm pinout compatibility with existing schematics.

Selection Notes

Select this component when a 48-bit parallel interface is required for display drivers. Compare against the DS90CR486 family variants to determine if the VSOP package meets space constraints. Evaluate the power consumption requirements relative to other deserializers in the portfolio. Verify that the 133 MHz bandwidth satisfies the resolution and refresh rate needs of the target application.

Part Context

This part belongs to the National Semiconductor Channel Link family, now managed by Texas Instruments following their acquisition. The DS90CR486 series is designed specifically for high-performance display applications. It serves as the receiver counterpart to the DS90CR483 transmitter. The NOPB suffix indicates compliance with RoHS standards and absence of lead-based materials.

Replacement Considerations

Direct replacements include the DS90CR486VS/NOPB without suffix variations. Check for newer revisions within the DS90CR486 family for potential pin-compatible upgrades. Consider the DS90CR286 or DS90CF386 families if fewer bits are sufficient for the application.
