Chip Scale Series Termination Array
CSPST
Features
• 8 or 16 integrated high frequency series
terminations
• Ultra small footprint Chip Scale Package
• Ceramic substrate
• 0.35mm Eutectic Solder Bumps, 0.65mm pitch
Product Description
The CSPST is a high performance Integrated Passive
Device (IPD) which provides series terminations suitable
for use in high speed bus applications. Eight (8) or
sixteen (16) series termination versions are provided.
These resistors provide excellent high frequency
performance in excess of 3GHz and are manufactured to
an absolute tolerance as low as ±1%. The Chip Scale

Applications
• Series resistive bus termination
• Isolated resistor array
Package provides an ultra small footprint for this IPD
and provides minimal parasitics compared to conventional packaging. Typical bump inductance is less than
25pH. The large solder bumps and ceramic substrate
allow for standard attachment to laminate printed circuit
boards without the use of underfill.
