DS90LV028AQDQFRQ1

Overview

The DS90LV028AQDQFRQ1 is an automotive-grade dual differential line receiver from Texas Instruments, designed for high-speed data transmission. It operates on a 3.3 V supply with a maximum voltage of 3.6 V and supports data rates exceeding 400 Mbps (200 MHz). The device features a maximum propagation delay of 2.5 ns and accepts LVDS, CML, or LVPECL input signals. It converts low-voltage differential inputs into 3 V CMOS outputs. Qualified under AEC-Q100 Grade 2, it functions within a temperature range of -40°C to +105°C. The component is housed in an 8-pin WSON (DQF) package measuring 2.00 mm x 2.00 mm.

Feature Summary

• AEC-Q100 qualified for automotive applications
• Supports switching rates greater than 400 Mbps
• Low power design with 18 mW static consumption at 3.3 V
• Flow-through pinout for simplified PCB layout

Applications

• Electronic point of sale (EPOS) applications
• Automotive infotainment systems
• Automotive instrument clusters
• Automotive head units

Procurement Notes

Verify the specific ordering suffix DQFRQ1 corresponds to the WSON-8 package and tape-and-reel quantity of 3000 units. Confirm that the RoHS compliance status and lead finish match project requirements. Ensure the operating temperature range aligns with the specified -40°C to +105°C automotive grade. Cross-reference the datasheet revision history for any updates to electrical characteristics or packaging details before finalizing procurement.

Selection Notes

Select this component when designing automotive interfaces requiring ultra-low power dissipation and noise immunity. It serves as a direct replacement for higher-power PECL/ECL devices in point-to-point configurations. Ensure the system utilizes controlled impedance 100 Ω differential traces and proper termination resistors near the receiver inputs. Verify that the driving source can provide the necessary differential voltage swing for reliable detection over the required common-mode range.

Part Context

This part belongs to the DS90LV028A-Q1 family of automotive LVDS receivers. It is specifically engineered for high-speed serial communication in vehicle electronics. The 'Q1' designation indicates automotive qualification, while 'DQF' specifies the WSON package type. It pairs with companion drivers like the DS90LV027AQ to form complete link solutions.

Replacement Considerations

The catalog version DS90LV028A offers similar functionality but lacks automotive qualification. For non-automotive designs, verify if standard commercial grade specifications meet the application needs. Other variants in the series may offer different package sizes or channel counts.
