SY10E451 SY100E451 FINAL 6-BIT REGISTER DIFFERENTIAL DATA CLOCK FEATURES DESCRIPTION ■ ■ ■ ■ ■ ■ 1100MHz min. toggle frequency Extended 100E VEE range of –4.2V to –5.5V Differential inputs: data and clock VBB output for single-ended use Asynchronous Master Reset Fully compatible with industry standard 10KH, 100K ECL levels ■ Internal 75KΩ input pulldown resistors ■ Fully compatible with Motorola MC10E/100E451 ■ Available in 28-pin PLCC package The SY10/100E451 offer six D-type flip-flops with singleended outputs and differential data and clock inputs, designed for use in new, high-performance ECL systems. The registers are triggered by the rising edge of the CLK input. A logic HIGH on the Master Reset (MR) input resets all outputs to a logic LOW. The VBB output is provided for use as a reference voltage for single-ended reception of ECL signals to that device only. When used for this purpose, it is recommended that VBB is decoupled to V CC via a 0.01µF capacitor.
