A high-speed, wide bandwidth data detection circuit includes a phase
detection module, a data detection module, a loop filter, and a voltage
controlled oscillator. The phase detection module is operably coupled to
produce a controlled current based on a current mode mathematical
manipulation of differences between an incoming data stream and a
recovered clock. The phase detection module performs the current mode
mathematical manipulations and produces the controlled current in the
current domain. The data detection module is operably coupled to produce
the detected data based on the incoming data stream and the recovered
clock. The loop filter is operably coupled to convert the controlled
current into a controlled voltage. The voltage controlled oscillator is
operably coupled to convert the control voltage into the recovered clock.
