| ERROR DETECTION/ CORRECTION CIRCUIT SY10E193 SY100E193 FEATURES s Hamming code generation s Extended 100E VEE range of -4.2V to -5.5V s s s s 8-bit wide Expandable for more width Provides parity register Fully compatible with industry standard 10KH, 100K ECL levels s Internal75K input pulldown resistors s Fully compatible with Motorola MC10E/100E193 s Available in 28-pin PLCC package DESCRIPTION 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.
