GHDD4414
Decision Circuit with Phase Detectors
GENERAL DESCRIPTION
Oki’s GHDD4414 is a 10-GHz decision circuit designed to strip data from high-speed serial bit streams in
10-Gbps communication links. Using a clock input at up to 10 GHz and using D-flip-flops, EX-ORs, and
phase detectors, this circuit separates a 10-Gbps data stream into: clock output, data output, “phase”
variation output, and data density output.
A 10-GHz master clock drives two D-flip-flops in this circuit. Buffered input data is clocked through the
first flip-flop, then the second, “data out” is taken from the first flip-flop. The data input buffer is com-
posed of a series of inverters to delay the signal and obtain a small decision ambiguity. A phase compar-
ison is made of the buffered data and data from flip-flop one; a second phase comparison is made of the
output of flip-flops one and two. The phase detectors are modified EX-OR circuits with resistor summing
of the logic gates to permit analog measurement of their outputs. Any change in the timing relationships
between the clock and data is seen at the output of the first phase detector. The second flip-flop operates
as a 1-bit shift register with fixed 360-deg phase shift. The second phase detector output depends only
upon the transition density (speed of rise and fall transitions) of the input data signal.
All signal interfaces are 50-
with all inputs internally terminated in 50
. The 10-GHz clock and data
inputs are AC capacitively-coupled for ease of interfacing at microwave speeds and reducing ground
noise induced phase jitter. Data and phase outputs are DC-coupled.
FEATURES
Phase detectors on chip: verifies data integrity
Isolated 10-Gbps input pins: minimizes noise
and impedance variation
1.5 V, 1 W: lowest power with 50-
interfaces
28-pin ceramic flat package with impedance
controlling ground plane and flush mount heat
sink
