NRND — plan the BOM line
The DS90LV047ATM: This means the part is still available for existing production but is not intended for new board spins — the manufacturer is winding down support, and a last-time-buy window may be open or closing. For a BOM that already carries this quad LVDS driver, the NRND status is a signal to secure inventory for the remaining production run or to evaluate a migration path.
Quad LVDS driver — 400 Mbps per channel
The DS90LV047ATM is a quad LVDS driver — four independent differential line drivers in one 16-SOIC package, each capable of 400 Mbps data rate. It converts a single-ended CMOS/TTL input into a low-voltage differential signal for point-to-point or multidrop backplane links.
Sourcing posture for an NRND part
Because the DS90LV047ATM is NRND, standard authorized-distributor channels may have limited or diminishing stock.
