Power Supply: Most negative power supply connection.

Serial Data Outputs (true and inverse). Pseudo-ECL differential outputs representing the serialized

data. These outputs require 390Ω pull down resistors.

Power Supply: Most positive power supply connection for the Serial Data ECL output buffers.

Power Supply: Most positive power supply connection for the Serial Clock ECL output buffers.

Serial Clock Outputs (inverse and true). Pseudo-ECL differential outputs of the Serial Clock (10x

Parallel Clock). These outputs require 390Ω pull-down resistors.

Power Supply: Most negative power supply connection.
