SEMICONDUCTOR TECHNICAL DATA ÷÷ 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. • • • • • • DW SUFFIX 20–LEAD PLASTIC SOIC WIDE PACKAGE CASE 751D–04 Differential Inputs and Outputs 20–Lead SOIC Packaging 700ps Typical Propagation Delays 50ps Output–Output Skews Low Voltage 100K ECL >2000V ESD Protection NC Q0 Q0 Q1 Q1 Q2 Q2 20 19 18 17 16 15 14 Q3 Q3 NC 13 12 11 PIN NAMES Pins Function Qna, Qna CLKn, CLKn Clk_Sel ÷1 ÷2 MR 1 2 NC 3 4 5 6 7 VCC CLK0 CLK0 Clk_Sel CLK1 CLK1 8 9 10 MR VEE NC Differential Clock Outputs Differential Clock Inputs Input Clock Selection ‘0’ Selects CLK0; ‘1‘ Selects CLK1 Asynchronous Master Reset ‘1’ Resets Dividers Figure 1. 20–Lead Pinout (Top View) MC100LVEL37 DC CHARACTERISTICS (VEE = –3.0V to –3.8V; VCC = GND) –40°C Symbol Characteristic IEE Power Supply Current IIH Input HIGH Current IINL Input LOW Current Min Typ 0°C Max Min 38 0.5 –300 Max Min 38 150 CLKn CLKn Typ 25°C 0.5 –300 5/97 4–1 Min REV 0 Typ Max 38 150 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)|.
