DS90C185SQX/NOPB

Overview

The DS90C185SQX/NOPB is a low-power serializer manufactured by Texas Instruments, designed for FPD-Link applications. It converts 28 LVCMOS parallel inputs into four high-speed LVDS differential outputs. The device supports data rates up to 2.94 Gb/s per channel pair. It operates within a supply voltage range of 1.71 V to 3.6 V and functions across an industrial temperature range of -40°C to +85°C. The component is housed in a compact 48-pin WQFN package with a 6x6 mm footprint, suitable for space-constrained portable electronics.

Feature Summary

• Converts wide parallel LVCMOS data streams into serial LVDS signals for long-distance transmission
• Integrates clock recovery circuitry to synchronize output data with the embedded clock signal
• Features low power consumption optimized for battery-operated mobile devices

Applications

• Mobile phone camera interfaces connecting image sensors to application processors
• Portable media players requiring high-bandwidth video data transfer
• Tablet computers utilizing internal display or camera link architectures

Procurement Notes

Verify that the suffix 'SQX' denotes the specific tape-and-reel packaging variant distinct from the 'SQE' cut-tape version. Confirm the manufacturer designation as Texas Instruments, resulting from the National Semiconductor acquisition. Ensure the RoHS compliance status matches current regulatory requirements for the intended market. Cross-reference the datasheet revision date to confirm pinout and electrical characteristics remain unchanged.

Selection Notes

Select this component when interfacing 28-bit parallel cameras with LVDS receivers in mobile form factors. It is appropriate for designs requiring single-link FPD-Link connectivity with minimal external components. Consider the WQFN package thermal performance during PCB layout. Verify that the host processor supports the required LVCMOS input levels and clock frequencies for the target data rate.

Part Context

This part belongs to the DS90C185 series of FPD-Link serializers. It serves as the transmitter side of the link, complementing deserializers like the DS90CR185. The series enables high-speed, low-noise communication between imaging sensors and baseband processors in consumer electronics.

Replacement Considerations

The DS90C185SQE/NOPB is a compatible alternative differing primarily in shipping packaging configuration rather than functional specifications.
