FGA Series ASPECT^TMECL Gate Arrays

General Description

The FGA Series is a new generation of ECL gate arrays

based on National’s ASPECT process. These advanced

ECL gate arrays, ranging from 200 to over 30,000 equiva-

lent gates, offer typical internal propagation delays of

150 ps and consume thirty percent less power than conven-

tional ECL arrays. (Refer to Table I.)

All FGA Series products interface with ECL 100K, ECL 10K

and ECL 10KH components, and, except for the FGA200,

FGA14000, FGA14040R, and FGA30000, are fully FAST

TTL compatible. The TTL interface eliminates requirements

for separate off-chip signal converters in mixed logic level

systems, thereby resulting in reduced board space and cost,

as well as avoiding the performance and reliability penalties

associated with off-chip signal converters.

With system clock frequencies up to 1.2 GHz, the speed

domain of Gallium Arsenide, FGA Series gate arrays are

especially well-suited for such high-performance applica-

tions as mainframe and supermini computers, fiber-optic

communications, and many military and aerospace systems.

In addition to providing superior speed/power performance

with high density, the ASPECT process is scalable to sub-

micron dimensions. FGA Series arrays are designed to ac-

commodate multiple ASPECT process generations to allow

designs implemented today to migrate to tomorrow’s arrays

based on future ASPECT processes.

With only internal cells and I/O cells, FGA Series arrays are

easy to use. Designers can implement logic using two-level

or three-level series gating circuit structures within an array,

with no complex signal mixing rules required. An extensive

macro library, common to all FGA Series arrays, contains

more than eighty SSI/MSI logic functions and 36 supporting

I/O macros. In addition, internal macros may be grouped to

form re-usable ‘‘soft macros’’ with even greater functional

complexity.

Features

New generation ECL gate arrays with complexity to

30,000 equivalent logic gates

Manufactured with 1.5-micron ASPECT process

CAD-programmable speed/power options

All FGA Series gate arrays feature CAD-programmable

speed/power options that allow the designer to maximize

performance by individually assigning the switching speed

and output drive currents for each internal macro. The

speed/power feature provides maximum ECL speed where

needed, yet allows overall chip power to remain at air-coola-

150 ps typical internal delay

Flexible array architecture with only two cell types:

Internal cells and I/O cells

F100K, 10K or 10KH ECL-compatible I/Os

Mixable ECL/TTL I/Os

Allows large number of simultaneously switching

outputs

ble levels. On-chip termination to 2V for the internal out-

put emitter followers further reduces power consumption.
