GTL, GTL+, AGTL+ Terminators Technical Data Features * 8 Bit, 16 Bit, and 32 BitTermination Sets * Compliant for GTL, GTL+, and AGTL+ Termination * Excellent High Frequency Performance * Slim BGA Package * 1% Resistor Tolerance * Low Channel to Channel Cross Talk Description These integrated termination networks provide high performance line termination for GTL, GTL+, and AGTL+ busses. The patented star circuit design combined with a ceramic substrate virtually eliminates cross talk between channels that is common in other termination networks and resistor arrays. The BGA packaging has been proven to reduce rework and improve reliability. Custom resistor values and tolerances available upon request. 8 Bit 16 Bit 32 Bit 3 3 3 2 2 2 1 1 A B C 1 A B C D E F A GTL+ Backplane Vtt Vtt Card Card C D E F G H J K L M Ordering Information Typical Application RT1451B6 B Card Card RT1451B6 Vtt Vtt Part Nu mber R Oh ms Bits Pitch(mm) RT1450B6 25 8 1.27 RT1451B6 25 16 1.27 RT1452B6 25 32 1.27 RT1453B6 56 8 1.27 RT1454B6 56 16 1.27 RT1427B6 56 32 1.27 RT1410B6 150 8 1.27 RT1411B6 150 16 1.27 RT1412B6 150 32 1.27 RT1412B7 150 32 1.00 (Tape and reel packaging information is shown on page 3) 1-3 (c) CTS Resistor Electrocomponents, 406 Parr Road, Berne Indiana, 46711 6/26/01 Tel: (219) 589-3111 Fax: (219) 589-3243 www.ctsclearone.com Mechanical Diagram L H RT14_ _B_ CTS YRWK W A1 Identifier K P (Pitch) P (Pitch) 1.27 mm Pitch D L W H P D K Coplanarity 3 x 3 Array (8 bit) mm inch 3.8 10.15 .15 0.0 06 3 .81 0.1 5 .150 .00 6 1 .32 0.1 5 .052 .00 6 1 .27 0.2 5 .050 .01 0 0 .76 0.0 5 .030 .00 2 0 .64 0.2 5 .025 .01 0 0.1 5 .00 6 3 x 6 Array (1 6 b it) mm inch 7.6 20.15 .30 0.0 06 3 .81 0.1 5 .150 .00 6 1 .32 0.1 5 .052 .00 6 1 .27 0.2 5 .050 .01 0 0 .76 0.0 5 .030 .00 2 0 .64 0.2 5 .025 .01 0 0.1 5 .00 6 3 x 1 2 Array (3 2 b it) mm inch 15.240 .15 .60 0.0 06 3 .81 0.1 5 .150 .00 6 1 .32 0.1 5 .052 .00 6 1 .27 0.2 5 .050 .01 0 0 .76 0.0 5 .030 .00 2 0 .64 0.2 5 .025 .01 0 0.1 5 .00 6 L W H P D K Copla narity 1 2.0 00.15 .472.006 3.000.15 .1 18.006 1.190.15 .0 47.006 1.000.25 .0 39.010 0.640.05 .0 25.002 0.500.25 .0 20.010 0.15 .006 1.0 0 m m Pitc h 3 x 12 Arra y (32 bit) mm inch Frequency Performance (50 ohm Network) Cross Talk Performance (50 ohm Network) F H Aggressor 1nS 250mV 100 D I A 90 E B C 80 70 Measured Voltage (Peak to Peak) Aggressor on Lead B 250mV 1nS Rise Time Measured Voltage (Peak to Peak) 40 Aggressor on Lead A 250mV 1nS Rise Time 30 Victim B 3.3 mV Victim A 3.2 mV Victim C 1.9 mV Victim C 2.7 mV Victim D 1.5 mV Victim D 1.8 mV Victim E 1.5 mV Victim E 1.4 mV Victim F 1.5 mV Victim F 1.5 mV Victim H 2.1 mV Victim H 1.5 mV Victim I 3.3 mV Victim I 2.0 mV 60 50 20 10 20 00 18 00 16 00 14 00 12 00 10 00 80 0 60 0 40 0 20 0 0 Electrical Specifications Resistor Tolerance: 1.0% Maximum Resistor Power: 0.05 Watts at 70C Temperature Coefficient of Resistance: 200 ppm/C Operating Temperature Range: -55C to +125C (Not to Exceed Maximum Package Power) Maximum Package Power (70C): 8 Bit = 0.3Watts 16 Bit = 0.6Watts 32 Bit = 1.2Watts 2-3 CTS Resistor Electrocomponents, 406 Parr Road, Berne Indiana, 46711 6/26/01 Tel: (219) 589-3111 Fax: (219) 589-3243 www.ctsclearone.com Recommended Land Pattern Solder Mask Dia. = Pad Diameter + .15 mm (.006 inch) Tape and Reel Packaging Part Number Coding 7 inch reel, Add TR7 to part number, example RT1450B6TR7 13 inch reel, Add TR13 to part number, example RT1450B6TR13 (bulk packaging is not available) Outline of Substrate TR13 Suffix PCB Pad Diameter Tape Width 24 mm Carrier Pitch 8 mm Reel Diameter Parts/Reel 13 inch 4,000 TR7 Suffix 1.00 mm Pitch (B7) = 0.51mm/.020 inch 1.27 mm Pitch (B6) = 0.64mm/.025 inch For .006" Thick Solder Paste Stencil, Aperture Opening Should be Equal to the PCB Pad Diameter.
