ERROR DETECTION/

CORRECTION CIRCUIT

SY10E193

SY100E193

FEATURES

DESCRIPTION

■ Hamming code generation

■ Extended 100E VEE range of –4.2V to –5.5V

■ 8-bit wide

The SY10/100E193 are error detection and correction

(EDAC) circuits designed for use in new, high- performance

ECL systems. The E193 generates hamming parity codes

on an 8-bit word as shown in the block diagram. The P5

output gives the parity of the whole word. PGEN provides

word parity after Odd/Even parity control and gating with

the BPAR input. PGEN also feeds into a 1-bit shiftable

The combinatorial part of the device generates the same

code pattern as the Motorola MC10193.

Used in conjunction with 12-bit parity generators, such

as the E160, a SECDED (single error correction, double

error detection) error system can be designed for a multiple

of an 8-bit word.

■ Expandable for more width

■ Provides parity register

■ Fully compatible with industry standard 10KH,

100K ECL levels

■ Internal75KΩ input pulldown resistors

■ Fully compatible with Motorola MC10E/100E193

■ Available in 28-pin PLCC package
