Name/Description

Positive Data Output.

Negative Data Output.

dc Supply Voltage.

Bias Reference Voltage. Connect to nominal –1.5 V stable voltage refer-

ence, bypassed to GND with a capacitor ≥0.047 µF.

Data Negative Reference. Internally bypassed with 110 pF. Broadband

operation requires up-close external bypassing with a capacitor ≥0.047 µF,

matching the input coupling capacitor.

Negative Data Input. Requires ac-coupling capacitor and 50 Ω source or

termination.

Positive Data Input.

Data Positive Reference. See pin 9 above.

Bias Force Voltage. Obsolete function, do not connect.

Bias Sense Voltage. Internal test point, tracking VBR. Normally not con-

nected.

Ground. For optimum performance, package back should contact board

ground plane. (See the Mounting and Connections section.)
