FEaTURES
■
This BGA packaging resistor network device virtually eliminates
channel capacitance, a primary cause of reduced system
performance
■
This device eases routing design of DDR SDRAM termination
■
Higher integration of resistor elements saves overall
assembly costs
■
BGA packaging is effective in saving of board space
and high density mounting
■
High precision ±1% resistance tolerance is standard
■
Ideal for use as DDR SDRAM Terminator and in
high speed digital circuits, etc .
■
Meets or exceeds IEC 60115-1, JIS C 5201-1, MIL-STD-202F
■
Rated ambient temperature: -70°C
■
Operating temperature range: -55°C…+125°C
