DS90UB638TRGZRQ1

Overview

The DS90UB638-Q1 is a single-input deserializer supporting FPD-Link III interfaces with MIPI CSI-2 outputs. It operates at data rates up to 4.16 Gbps and supports scalable MIPI CSI-2 lane speeds of 400 Mbps, 800 Mbps, 1.5 Gbps, or 1.6 Gbps per lane. The device accommodates 1 to 4 data lanes and up to four virtual channels. It functions within an ambient temperature range of -40°C to +105°C and requires a VDD18 supply voltage between 1.71 V and 1.89 V. The component utilizes a 48-pin VQFN package measuring 7.00 mm by 7.00 mm.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official orderable addendum to confirm package type and tape/reel specifications. Ensure the component meets AEC-Q100 Grade 2 requirements for the intended automotive application environment. Cross-reference the datasheet revision history to validate compatibility with existing system designs.

Selection Notes

Select this deserializer when pairing with DS90UB635-Q1 serializers for high-resolution camera applications or DS90UB633A-Q1 for lower bandwidth sensors. Confirm that the downstream processor supports the required MIPI D-PHY version 1.2 interface. Evaluate power consumption requirements based on the selected VDD_SEL configuration and operating data rate.
