DS3885 BTL Arbitration Transceiver

General Description

The DS3885 is one in a series of transceivers designed spe-

Features

9-bit inverting BTL transceiver

cifically for the implementation of high performance Future-

Meets IEEE 1194.1 standard on Backplane Transceiver

Logic (BTL)

bus and proprietary bus interfaces. The DS3885 Arbitra-

tion Transceiver is designed to conform to IEEE 1194.1

(Backplane Transceiver LogicÐBTL) as specified in the

Includes on chip competition logic and parity checking

Supports live insertion

IEEE 896.2 Futurebus

Transceiver incorporates the competition logic internally

specification. The Arbitration

Glitch free power-up/down protection

Typically less than 5 pF bus-port capacitance

Low bus-port voltage swing (typically 1V) at 80 mA

Open collector bus-port output allows Wired-OR

connection

which simplifies the implementation of a Futurebus appli-

cation by minimizing the on board logic required.

The DS3885 driver output configuration is an NPN open col-

lector which allows Wired-OR connection on the bus. Each

driver output incorporates a Schottky diode in series with its

collector to isolate the transistor output capacitance from

the bus thus reducing the bus loading in the inactive state.

Exceeds 2 kV ESD testing (Human Body Model)

Individual bus-port ground pins minimize ground bounce

Controlled rise and fall time to reduce noise coupling to

adjacent lines

The BTL drivers also have high sink current capability to

comply with the bus loading requirements defined within

IEEE 1194.1 BTL specification.

TTL compatible driver and control inputs

Built in bandgap reference with separate QV

QGND pins for precise receiver thresholds

Backplane Transceiver Logic (BTL) is a signaling standard
