1. SCOPE
This document describes the electrical characteristics of the KGL4223.
2. PRODUCT NAME
KGL4223
3.
FUNCTIONS
This device converts 8bit parallel streams into one stream up to 5GHz clock frequency.
Complementary output data are synchronized with an input clock. Parallel data
loading is accomplished synchronously with an internal 1/8 clock, which is generated
by dividing the input clock on chip.
Functional diagram and time chart are indicated Figure1 and Figure2.
