What this quad LVDS receiver does on a high-speed serial link
The SN65LVDS390PW is a four-channel LVDS receiver from TI's 65LVDS family, designed to convert differential LVDS signals back to single-ended CMOS logic levels on the receiving end of a point-to-point or multi-drop link. It handles data rates up to 200 Mbps per channel, which covers common video interfaces, backplane clock distribution, and high-speed sensor data streams where the differential swing keeps noise coupling low. With four receivers in one 16-TSSOP package, it saves board area compared to using four separate single-channel parts.
Data rate, channel count, and what they mean for your link budget
Each of the four receiver channels is rated for 200 Mbps. At that speed, the LVDS differential swing (~350 mV typical) keeps the signal integrity clean over a few meters of twisted-pair or PCB trace, provided the termination resistor is placed at the far end of the line. The 200 Mbps ceiling means this part suits applications like 24-bit RGB video at 60 Hz (roughly 150 Mbps per channel) or aggregating multiple 100 Mbps Ethernet-like serial streams. The 0/4 driver/receiver count tells you this is a receive-only device — there are no drivers on-chip. If your link needs bidirectional communication, you pair it with a separate LVDS driver like the SN65LVDS391.
Supply voltage, temperature range, and where this part fits on the board
No external LDO needed if the 3.3V rail is clean. Place the part close to the connector or cable entry to keep the differential trace length short before termination. Decouple with a 0.1 µF ceramic near each supply pin.
