GTL, GTL+, AGTL+ Terminator Technical Data Features * * 8 Bit, 16 Bit, and 32 Bit Termination 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 Style D 16 Bit Style D 32 Bit Style D 3 3 3 2 2 2 1 1 A B 1 A C B C D E F A Typical Application Ca rd Ca rd C D E F G H J K L M Ordering Information G TL+ B ac k pla ne RT1 4 5 1B 6 B Ca rd Ca rd RT1 4 5 1B 6 V tt V tt V tt V tt Part Number RT1450B6 RT1451B6 RT1452B6 RT1453B6 RT1454B6 RT1427B6 RT1410B6 RT1411B6 RT1412B6 RT1412B7 R Ohms 25 25 25 56 56 56 150 150 150 150 Bits 8 16 32 8 16 32 8 16 32 32 1-3 (c) 2005 CTS Corporation.
