BTL TURBOTRANSCEIVER

General Description

™

The bus driver is an open collector NPN with a Schottky

diode in series to isolate the transistor output capacitance

from the bus when the driver is in the inactive state. The

active output low voltage is typically 1V. The bus is intended

to be operated with termination resistors (selected to match

the bus impedance) to 2.1V at both ends. Each of the

resistors can be as low as 20Ω.

The TURBOTRANSCEIVER is designed for use in very high

speed bus systems. The bus terminal characteristics of the

TURBOTRANSCEIVER are referred to as “Backplane

Transceiver Logic” (BTL). BTL is a new logic signaling stan-

dard that has been developed to enhance the performance

of backplane buses. BTL compatible transceivers feature

low output capacitance drivers to minimize bus loading, a 1V

nominal signal swing for reduced power consumption and

receivers with precision thresholds for maximum noise im-

munity. This new standard eliminates the settling time de-

lays, that severely limit the TTL bus performance, to provide

significantly higher bus transfer rates.

Features

n Fast single ended transceiver (typical driver enable and

receiver propagation delays are 3.5 ns and 5 ns)

n Backplane Transceiver Logic (BTL) levels (1V logic

swing)

n Less than 5 pF bus-port capacitance

n Drives densely loaded backplanes with equivalent load

impedances down to 10Ω

n 4 transceivers in 20 pin PCC package

n Specially designed for stripline backplanes

n Separate bus ground returns for each driver to minimize

ground noise

The TURBOTRANSCEIVER is compatible with the require-

ments of the proposed IEEE 896 Futurebus draft standard. It

™

is similar to the DS3896/97 BTL TRAPEZOIDAL Trans-

ceivers but the trapezoidal feature has been removed to

improve the propagation delay. A stripline backplane is there-

fore required to reduce the crosstalk induced by the faster

rise and fall times. This device can drive a 10Ω load with a

typical propagation delay of 3.5 ns for the driver and 5 ns for

the receiver.

n High impedance, MOS and TTL compatible inputs

™

n TRI-STATE control for receiver outputs

When multiple devices are used to drive a parallel bus, the

driver enables can be tied together and used as a common

control line to get on and off the bus. The driver enable delay

is designed to be the same as the driver propagation delay in

order to provide maximum speed in this configuration. The

low input current on the enable pin eases the drive required

for the common control line.

n Built-in bandgap reference provides accurate receiver

threshold

n Glitch free power up/down protection on all outputs

n Oxide isolated bipolar technology
