DUALTHÉVENINTERMINATION NETWORK

Features

Applications

• Stable resistor network

• SCSI termination

• 18 terminating lines/package

• Thévenin termination

• Saves board space and reduces assembly cost

Product Description

Why thin film resistor networks? A terminating resistor is

used to reduce or eliminate unwanted reflections on a

transmission line. It can perform this function only when

its resistance value matches the characteristic imped-

ance of the transmission line. The resistors used for

terminating the transmission lines should be noiseless,

stable and functional at high frequencies. Unlike thin

film-based resistor networks, conventional thick film

resistors used for terminating transmission lines are not

stable over temperature and time and impose system

performance limitations at very high frequencies.

Peripheral devices like disk drives, printers, and CD

ROMs are connected to host through a special bus

called SCSI (Small Computer System Interface). The fast

edge rated signals that are transmitted through the SCSI

cable generate ringing on the bus. This will slow down

communication between host and peripherals. The SCSI

standard recommends proper resistor (Thévenin)

termination at host and peripheral locations to eliminate

transmission line effects.

CAMDs PRN102/112 Dual Thévenin Termination

Networks offer high integration and performance in a

miniature QSOP or SOIC package, which saves critical

board area and provides manufacturing cost and

reliability efficiencies.
