DS15BA101 1.5 Gbps Differential Buffer with Adjustable Output Voltage

Check for Samples: DS15BA101

FEATURES

DESCRIPTION

The DS15BA101 is a high-speed differential buffer for

• Data Rates from DC to 1.5+ Gbps

cable driving, level translation, signal buffering, and

• Differential or Single-ended Input

signal repeating applications. Its fully differential

• Adjustable Output Amplitude

signal path ensures exceptional signal integrity and

noise immunity and it drives both differential and

• Single 3.3V Supply

single-ended transmission lines at data rates in

• Industrial -40°C to +85°C Temperature

excess of 1.5 Gbps.

• Low Power: 150 mW (typ) at 1.5 Gbps

Output voltage amplitude is adjustable via a single

DS15BA101 SNLS234J – OCTOBER 2006 – REVISED APRIL 2013 www.ti.com DEVICE OPERATION INPUT INTERFACING The DS15BA101 accepts either differential or single-ended input. The inputs are self-biased, allowing for simple AC or DC coupling. DC-coupled inputs must be kept within the specified common-mode range. The IN+ and INpins are self-biased at approximately 2.1V with VCC = 3.3V. The following three figures illustrate typical DCcoupled interface to common differential drivers.
