MAX9381 19-2397 Rev 0 4/02 Lowest Power 3.0GHz ECL/PECL Differential Data and Clock D Flip-Flop General Description Features The MAX9381 differential data, differential clock D flip- 3.0GHz Guaranteed Operating Clock Frequency flop is pin compatible with the ON Semiconductor 0.2ps Added Random Jitter RMS MC100EP52, with the added benefit of a wider supply- voltage range from 2.25V to 5.5V and 25% lower supply 328ps Typical Propagation Delay current. Data enters the master part of the flip-flop PECL Operation from V = 2.25V to 5.5V with CC when the clock is low and is transferred to the outputs upon a positive transition of the clock. Interchanging V = 0V EE the clock inputs allows the part to be used as a nega- ECL Operation from V = -2.25V to -5.5V with EE tive edge-triggered device. The MAX9381 utilizes input V = 0V CC clamping circuits that ensure the stability of the outputs when the inputs are left open or at V . Input Safety Clamps Ensure Output Stability when EE Inputs are Open or at V EE The MAX9381 is offered in an 8-pin SO package and the smaller 8-pin MAX package. 2kV ESD Protection (Human Body Model) Applications Precision Clock and Data Distribution Central Office Ordering Information DSLAM PART TEMP RANGE PIN-PACKAGE DLC MAX9381ESA -40C to +85C 8 SO MAX9381EUA* -40C to +85C 8 MAX Base Station *Future productcontact factory for availability.
