Preliminary
This version:
Dec. 2000
10Gb/s/ 12.5Gb/s 8:1 Multiplexer
GENERAL DESCRIPTION
The KGL4201/KGL4201C converts low-speed 8bit parallel data streams into high-speed serial data stream
up to 10Gb/s/ 12.5Gb/s. Parallel input data loading is synchronized with the internal 1/8 clock generated from
an input clock on chip. Serial output data are synchronized with the input clock. The device is ideal for use in
the 10Gb/s/ 12.5Gb/s optical communication systems.
FEATURES
•
High speed operation
•
Single power supply voltage
•
Low power dissipation
•
Rise/Fall time
•
Complementary serial data outputs
•
