xDSL line driver in 14-TSSOP — 2/0 configuration
The AD8019ARU-REEL is an Analog Devices xDSL line driver in a 14-TSSOP package, providing two drivers and zero receivers — a transmit-only interface for DSL line-card or CPE applications where the upstream path is handled by a separate receiver channel. Rated for a supply range of 5V to 12V, the driver accommodates the common xDSL line voltages used in central-office and customer-premises equipment, with the 14-TSSOP footprint keeping the board area tight for multi-channel designs.
Package and supply — board-fit details
Housed in a 14-TSSOP (0.173", 4.40mm width) surface-mount package, the AD8019ARU-REEL mates to a standard 14-pin TSSOP land pattern — the 0.65 mm pitch requires no special via fan-out for the supply and output traces, simplifying the PCB layout for a two-layer board. The 5V to 12V supply range means the driver can be powered from the same 12V rail as the line transformer or from a lower 5V digital supply, depending on the output swing needed for the DSL protocol.
