LVDS driver for high-speed serial links
The Texas Instruments DS90LV047ATM/DRPB is a four-channel LVDS driver designed to convert parallel CMOS/TTL data into a low-voltage differential signal for high-speed serial transmission. It handles a per-channel data rate of 400 Mbps, making it suitable for applications like flat-panel display interfaces, backplane interconnects, and clock distribution where signal integrity over twisted-pair or PCB traces matters.
At 400 Mbps, the driver's output transition times are fast enough that PCB trace length matching and impedance control become critical. The LVDS swing keeps EMI low, but the edge rate means a poorly terminated stub can reflect energy back and close the eye. The 4/0 driver/receiver count means this is a transmit-only device — the receiving end needs a separate LVDS receiver to complete the link.
No last-time-buy window remains open; the buyer should evaluate a replacement for new designs or long-term production support.
