1.5 Gbps Differential Buffer with Adjustable Output Voltage
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
up to 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
The DS15BA101 is powered from a single 3.3V supply and
consumes 150 mW (typ) at 1.5 Gbps. The DS15BA101 op-
erates over the full −40°C to +85°C industrial temperature
range and is available in a space saving 3x3 mm LLP-8 pack-

Note 1: "Absolute Maximum Ratings" are those parameter values beyond which the life and operation of the device cannot be guaranteed. The stating herein of
these maximums shall not be construed to imply that the device can or should be operated at or beyond these values. The table of "Electrical Characteristics"
specifies acceptable device operating conditions.
Note 2: Current flow into device pins is defined as positive. Current flow out of device pins is defined as negative. All voltages are stated referenced to GND.
Note 3: Typical values are stated for VCC = +3.3V and TA = +25°C.
Note 4: Specification is guaranteed by characterization.
Note 5: Maximum ICC is measured at VCC = +3.465V and TA = +70°C.
Note 6: Specification is guaranteed by characterization and verified by test.
