DS15BA101
1.5 Gbps Differential Buffer with Adjustable Output Voltage
General Description
The DS15BA101 is a high-speed differential buffer for cable
driving, level translation, signal buffering, and signal repeat-
ing applications. Its fully differential signal path ensures ex-
ceptional signal integrity and noise immunity and it drives both
differential and single-ended transmission lines at data rates
in excess of 1.5 Gbps.
Output voltage amplitude is adjustable via a single external
resistor for level translation and cable driving applications into
50-ohm single-ended and 100-ohm differential mode
impedances.
The DS15BA101 is powered from a single 3.3V supply and
consumes 150 mW (typ) at 1.5 Gbps. It operates over the full
−40°C to +85°C industrial temperature range and is available
in a space saving 3x3 mm LLP-8 package.
