| MOTOROLA SEMICONDUCTOR TECHNICAL DATA Low Voltage 1:9 Differential ECL/PECL Clock Driver The MC100LVE111 is a low skew 1-to-9 differential driver, designed with clock distribution in mind. The MC100LVE111's function and performance are similar to the popular MC100E111, with the added feature of low voltage operation. It accepts one signal input, which can be either differential or single-ended if the VBB output is used. The signal is fanned out to 9 identical differential outputs.

Optimal design and layout serve to minimize gate to gate skew within a device, and empirical modeling is used to determineprocess control limits that ensure consistent tpd distributions from lot to lot. The net result is a dependable, guaranteed low skew device. To ensure that the tight skew specification is met it is necessary that both sides of the differential output are terminated into 50, even if only one side is being used. In most applications, all nine differential pairs will be used and therefore terminated. In the case where fewer than nine pairs are used, it is necessary to terminate at least the output pairs on the same package side as the pair(s) being used on that side, in order to maintain minimum skew. Failure to do this will result in small degradations of propagation delay (on the order of 10-20ps) of the output(s) being used which, while not being catastrophic to most designs, will mean a loss of skew margin. FN SUFFIX PLASTIC PACKAGE CASE 776-02 The MC100LVE111, as with most other ECL devices, can be operated from a positive VCC supply in PECL mode. This allows the LVE111 to be used for high performance clock distribution in +3.3V systems. Designers can take advantage of the LVE111's performance to distribute low skew clocks across the backplane or the board. In a PECL environment, series or Thevenin line terminations are typically used as they require no additional power supplies. For systems incorporating GTL, parallel termination offers the lowest power by taking advantage of the 1.2V supply as a terminating voltage. For more information on using PECL, designers should refer to Motorola Application Note AN1406/D. 12/94 (c) Motorola, Inc. 1996 4-1 REV 1 MC100LVE111 Q0 25 VEE 26 27 28 1 2 3 4 5 Q8 Q0 24 Q1 VCCO Q1 23 22 21 Q2 20 Q2 19 18 17 16 Q3 Q3 Q4 VCCO Q4 Q5 Q5 PIN NAMES Pins IN, IN Q0, Q0-Q8, Q8 VBB Function NC IN Differential Input Pair Differential Outputs VBB Output VCC IN VBB NC Pinout: 28-Lead PLCC (Top View) 15 14 13 12 6 Q8 7 Q7 8 9 10 Q6 11 Q6 VCCO Q7 LOGIC SYMBOL Q0 Q0 Q1 Q1 Q2 Q2 Q3 Q3 IN IN Q4 Q4 Q5 Q5 Q6 Q6 Q7 Q7 Q8 VBB Q8 MOTOROLA 4-2 ECLinPS and ECLinPS Lite DL140 -- Rev 3 MC100LVE111 ECL DC CHARACTERISTICS -40C Symbol VOH VOL VIH VIL VBB VEE IIH IEE Characteristic Output HIGH Voltage Output LOW Voltage Input HIGH Voltage Input LOW Voltage Output Reference Voltage Power Supply Voltage Input HIGH Current Power Supply Current 55 Min -1.025 -1.810 -1.165 -1.810 -1.38 -3.0 Typ -0.955 -1.705 Max -0.880 -1.620 -0.880 -1.475 -1.26 -3.8 150 66 55 Min -1.025 -1.810 -1.165 -1.810 -1.38 -3.0 0C Typ -0.955 -1.705 Max -0.880 -1.620 -0.880 -1.475 -1.26 -3.8 150 66 55 Min -1.025 -1.810 -1.165 -1.810 -1.38 -3.0 25C Typ -0.955 -1.705 Max -0.880 -1.620 -0.880 -1.475 -1.26 -3.8 150 66 65 Min -1.025 -1.810 -1.165 -1.810 -1.38 -3.0 85C Typ -0.955 -1.705 Max -0.880 -1.620 -0.880 -1.475 -1.26 -3.8 150 78 Unit V V V V V V A mA PECL DC CHARACTERISTICS -40C Symbol VOH VOL VIH VIL VBB VCC IIH IEE Characteristic Output HIGH Voltage1 Output LOW Voltage1 Input HIGH Voltage1 Input LOW Voltage1 Output Reference Voltage1 Power Supply Voltage Input HIGH Current Power Supply Current 55 Min 2.275 1.490 2.135 1.490 1.92 3.0 Typ 2.345 1.595 Max 2.420 1.680 2.420 1.825 2.04 3.8 150 66 55 Min 2.275 1.490 2.135 1.490 1.92 3.0 0C Typ 2.345 1.595 Max 2.420 1.680 2.420 1.825 2.04 3.8 150 66 55 Min 2.275 1.490 2.135 1.490 1.92 3.0 25C Typ 2.345 1.595 Max 2.420 1.680 2.420 1.825 2.04 3.8 150 66 65 Min 2.275 1.490 2.135 1.490 1.92 3.0 85C Typ 2.345 1.595 Max 2.420 1.680 2.420 1.825 2.04 3.8 150 78 Unit V V V V V V A mA 1.

The differential propagation delay is defined as the delay from the crossing points of the differential input signals to the crossing point of the differential output signals. See Definitions and Testing of ECLinPS AC Parameters in Chapter 1 (page 1-12) of the Motorola High Performance ECL Data Book (DL140/D). 2. The single-ended propagation delay is defined as the delay from the 50% point of the input signal to the 50% point of the output signal. See Definitions and Testing of ECLinPS AC Parameters in Chapter 1 (page 1-12) of the Motorola High Performance ECL Data Book (DL140/D). 3. The within-device skew is defined as the worst case difference between any two similar delay paths within a single device. 4. VPP(min) is defined as the minimum input differential voltage which will cause no increase in the propagation delay. The VPP(min) is AC limited for the E111 as a differential input as low as 50 mV will still produce full ECL levels at the output. 5. VCMR is defined as the range within which the VIH level may vary, with the device still meeting the propagation delay specification. The VIL level must be such that the peak to peak voltage is less than 1.0 V and greater than or equal to VPP(min).
