SY10E193 SY100E193 SY10E193 ERROR DETECTION/ CORRECTION CIRCUIT FEATURES SY100E193 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. ■ ■ ■ ■ 8-bit wide 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 PIN NAMES Pin M9999-032006 [email protected] or (408) 955-1690 Function B0–B7 Check Bit Inputs BPAR Check Bit Parity Input EV/OD Even/Odd Parity Select EN Parity Enable HOLD Syndrome Hold Input S-IN Syndrome Bit Input SHIFT Syndrome Bit Shift CLK Clock Input P1–P5 Parity Output PGEN Parity Generate Output PARERR/PARERR Parity Error Output VCCO VCC to Output Rev.: F 1 Amendment: /0 Issue Date: March 2006 SY10E193 SY100E193 Micrel, Inc.
