DESCRIPTION
■ Hamming code generation
■ Extended 100E VEE range of –4.2V to –5.5V
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
register for use as part of a scan ring.
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.
