12-BIT PARITY GENERATOR/CHECKER Micrel, Inc. FEATURES The SY10/100E160 are high-speed, 12-bit parity generator/checkers with differential outputs, for use in new, high-performance ECL systems. The output Q takes on a logic HIGH value only when an odd number of inputs are at a logic HIGH. A logic HIGH on the enable input (EN) forces the output Q to a logic LOW. An additional feature of the E160 is the output register. Two multiplexers and their associated signals control the register input by providing the option of holding present data, loading the new parity data or shifting external data in. To hold the present data, the Hold signal (HOLD) must be at a logic LOW level. If the HOLD signal is at a logic HIGH, the data present at the Q output is passed through the first multiplexer. Taking the Shift signal (SHIFT) to a logic HIGH will shift the data at the S-IN pin into the output register. If the SHIFT signal is at a logic LOW, the output of the first multiplexer is then passed through to the register. The register itself is clocked on the rising edge of CLK1 or CLK2 (or both). The presence of a logic HIGH on the reset pin (R) forces the register output Y to a logic LOW. ■ ■ ■ ■ ■ ■ Output register with Shift/Hold capability 900ps max.
