NOT RECOMMENDED FOR NEW DESIGNS SY10E451 Micrel, Inc. 6-BIT REGISTER SY1S0YE10405E1451 DIFFERENTIAL DATA CLOCK SY100E451 FEATURES DESCRIPTION (cid:1) 1100MHz min. toggle frequency The SY10/100E451 offer six D-type flip-flops with single- (cid:1) Extended 100E V range of –4.2V to –5.5V ended outputs and differential data and clock inputs, EE designed for use in new, high-performance ECL systems. (cid:1) Differential inputs: data and clock The registers are triggered by the rising edge of the CLK (cid:1) VBB output for single-ended use input. (cid:1) Asynchronous Master Reset A logic HIGH on the Master Reset (MR) input resets all (cid:1) Fully compatible with industry standard 10KH, outputs to a logic LOW. The VBB output is provided for use 100K ECL levels as a reference voltage for single-ended reception of ECL (cid:1) Internal 75KΩ input pulldown resistors signals to that device only. When used for this purpose, it is recommended that V is decoupled to V via a 0.01µF (cid:1) Fully compatible with Motorola MC10E/100E451 capacitor.
