| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Product Preview 1:4 /1//2 ECL/PECL Clock MC100LVEL37 Fanout Buffer The MC100LVEL37 is a fully differential 1:4 fanout buffer. The device offers two outputs at /1 of the input frequrency, and two outputs at /2 of the input frequency. The Low Output-Output Skew of the device makes it ideal for distributing1x and 1/2x frequency synchronous signals. The differential inputs have special circuitry which ensures device stability under open input conditions. When both differential inputs are left open the D input will pull down to VEE, The D input will bias around VCC/2 and the Q output will go LOW. * * * * * * Differential Inputs and Outputs 20-Lead SOIC Packaging 700ps Typical Propagation Delays 50ps Output-Output Skews Low Voltage 100K ECL >2000V ESD Protection DW SUFFIX 20-LEAD PLASTIC SOIC WIDE PACKAGE CASE 751D-04 NC 20 Q0 19 Q0 18 Q1 17 Q1 16 Q2 15 Q2 14 Q3 13 Q3 12 NC 11 PIN NAMES Pins Qna, Qna CLKn, CLKn Clk_Sel MR Function Differential Clock Outputs Differential Clock Inputs Input Clock Selection `0' Selects CLK0; `1` Selects CLK1 Asynchronous Master Reset `1' Resets Dividers /1 /2 1 NC 2 3 4 5 6 7 8 MR 9 VEE 10 NC VCC CLK0 CLK0 Clk_Sel CLK1 CLK1 Figure 1. 20-Lead Pinout (Top View) MC100LVEL37 DC CHARACTERISTICS (VEE = -3.0V to -3.8V; VCC = GND) -40C Symbol IEE IIH IINL Characteristic Power Supply Current Input HIGH Current Input LOW Current CLKn CLKn 0.5 -300 Min Typ 38 150 0.5 -300 Max Min 0C Typ 38 150 0.5 -300 Max Min 25C Typ 38 150 0.5 -300 Max Min 85C Typ 38 150 Max Unit mA A A This document contains information on a product under development.

Minimum input swing for which AC parameters guaranteed. The device has a DC gain of 40. 2. The CMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within the specified range and the peak-to-peak voltage lies between VPPmin and 1V. The lower end of the CMR range varies 1:1 with VEE. The numbers in the spec table assume a nominal VEE = -3.3V. Note for PECL operation, the VCMR(min) will be fixed at 3.3V - |VCMR(min)|.
