Title of Invention

AN APPARATUS AND A METHOD OF FILTERING A PHASE ERROR SIGNAL

Abstract 1. An apparatus for filtering a phase error signal, comprising: a first filter subcircuit receiving a phase error signal from a phase comparator and filtering the error signal with the first filter subcircuit when enabled; a second filter subcircuit receiving the phase error signal from the phase comparator and filtering the error signal with the second filter subcircuit when enabled; and a first enable switch and a second enable switch which are activated in , combination to control filtering of the error signal; wherein the first filter subcircuit is enabled by activating a first combination of ) the first and second enable switches and the second filter subcircuit is enabled by activating a second combination of the first and second enable switches. 2. The apparatus of claim 1, wherein the second filter subcircuit has a higher 2 bandwidth than the first filter subcircuit and the second filter subcircuit is momentarily . activated to fast acquisition with the first filter subcircuit. 3. The apparatus of claim 1, further comprising a fast acquisition subcircuit 2 including a fast acquisition enable switch and wherein fast acquisition of one of the first and second filter subcircuits is enabled when the fast acquisition switch is activated.
