It handles serial data at rates up to 400 Mbps per channel, making it a fit for point-to-point or multidrop backplane links in industrial control, video distribution, and telecom line cards.
Full duplex and 2/2 configuration — the bus architecture decision
Full-duplex operation means each channel can transmit and receive simultaneously, which halves the cable count compared to a half-duplex link that needs direction control. With two independent driver/receiver pairs, this part can serve two separate full-duplex links or one link with a redundant path. The 400 Mbps per channel is the raw bit rate; at that speed, the LVDS swing is typically 350 mV differential, keeping EMI low and allowing cable runs of several meters with proper termination.
The NOPB suffix confirms ROHS3 compliance, which means no lead in the solder finish — relevant for RoHS-driven builds. For volume commitments, the base product number DS90LV049 covers multiple package and temperature variants, so a single qualification covers the family.
Package and footprint — 16-TSSOP on a 4.40 mm body
The 0.173" body height keeps it low-profile for mezzanine cards or tight enclosures. For a layout engineer, the decoupling recommendation is a 0.1 µF ceramic per supply pin placed within 2 mm of the pin; the supply range of 3V to 3.6V means a 3.3V rail with ±5% tolerance is safe without an extra LDO.
