The supply voltage spans 2.25 V to 3.63 V, covering both 2.5 V and 3.3 V rails without an external regulator — one less part on the BOM for a mixed-voltage system.
The 6-SMD no-lead exposed pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm — the exposed pad aids thermal conduction to the PCB ground plane.
Yes, it carries AEC-Q100 rating, meaning it has passed automotive-grade reliability tests including temperature cycling, ESD, and latch-up. This qualifies it for under-hood and chassis-domain applications where the ambient temperature can reach 85°C.
The wide tolerance also helps if the supply has ripple or droop.
Yes, the Enable/Disable function lets you hold the LVDS output in high-Z. When disabled, the supply current drops from 32 mA (max) to 22 mA (max), saving power in sleep or standby modes.
It outputs LVDS (Low-Voltage Differential Signaling) at 312.5 MHz. LVDS provides low noise and fast edge rates, making it a common choice for clocking high-speed ADCs, FPGAs, and SerDes interfaces.
