VME64, VME64x Terminator Technical Data Sheet RoHS Compliant Parts Available Description This Thevenin termination network provides high performance resistor termination for VME64 and VME64x back planes. Features • • • • • • Designed with a ceramic substrate, this device minimizes parasitic capacitance and inductance, a primary cause of reduced system performance. In addition, the BGA package eases touting design, saving the designer many hours of printed circuit layout. 8-Bit Termination Network VME64, VME64x Compliant Low Channel Capacitance Laser Trimmed Resistance to ± 1% Slim BGA Package RoHS Compliant Designs Available • Compatible with both lead and lead free processes The BGA packaging has been proven to reduce rework and improve reliability Electrical Specifications Style G 3 R1 2 R2 1 A B C D E F G H Resistor Tolerance: ± 1.0% TCR Operating Temperature Range ± 200ppm/°C -55°C to +125°C Maximum Resistor Power: 0.05 Watts at 70°C Maximum Package Power: Process Requirements: 1.0 Watts at 70°C Maximum Re-flow Temperature Per IPC/JEDEC J-STD-020C Typical Applications VME64x Backplane 3.3V Card RT2211 Card Card Card 3.3V RT2211 Standard Termination VME64 Low Voltage Termination VME64x +5V +3.3V 330 220 470 1.8K RT2211 RT2210 Ordering Information Standard Part No. RT1210B7 RT1211B7 R1 Ω 330 220 R2 Ω 470 1800 Packaging Information Array Size 3x8 3x8 Pitch (mm) 1.00 1.00 RoHS Part No. RT2210B7 RT2211B7 TR7 TR13 Tape Width Suffix 24 mm 24mm Carrier Pitch 8 mm 8 mm Reel Diameter 7 inch 13 inch Parts/Reel 1,000 4,000 Part Number Coding 7 inch reel, Add TR7 to part number, example RT2210B7TR7 13 inch reel, Add TR13 to part number, example RT2210B7TR13 (Bulk packaging is not available) Direction of Feed CTS Electronic Components www.ctscorp.com © 2006 CTS Corporation.
