KGL4201
10-GHz 8:1 Multiplexer
GENERAL DESCRIPTION
Oki’s KGL4201 is a 10-GHz 8:1 multiplexer designed to operate in 10-Gbps communication links. This
circuit synchronously merges eight 1.25-Gbps data streams, clocked at low frequency rates into a single
10-Gbps stream, clocked at the higher frequency. In the KGL4201 multiplexer, the 10-GHz master clock is
first divided by two, then by four. The lower frequency components are first multiplexed by four, then
the two groups are merged into a single data stream using the master 10-Gbps clock. Complementary
1/8 synchronous clock outputs are made available from the KGL4201 for use in synchronizing lower fre-
quency logic.
with direct DC coupling on the 1.25-Gbps data inputs and phase-locked
1.25-Gbps clock outputs. The 10-Gbps data output and 10-GHz clock input are AC-capacitively-coupled
for ease of interfacing at microwave speeds and reducing ground noise induced phase jitter. All package
clock and data pins are separated by either ground or supply voltage pins to control the I/O impedance,
maintain signal isolation and reduce phase noise.
All signal interfaces are 50-
The KGL4201 is shipped in a 40-pin ceramic flat-package with impedance-controlling ground plane and
flush mounting bottom heat sink.
FEATURES
AC-coupled 10 Gbps I/O: eliminates DC
coupled phase jitter
1/8 clock generated on chip: easy to
synchronize downstream logic
2 V, 2.4 W
Isolated I/O pins: minimize noise and
impedance variation
Packaged in 40-pin ceramic flat-package with
ground plane and heat sink.
