A source synchronous architecture with constant and wide jitter-tracking bandwidth (JTB) is presented. The proposed receiver is based on an injection-locked oscillator (ILO), which provides jitter filtering and phase deskew simultaneously. While using only the ILO has intrinsic two dependence problems (JTB versus deskew and JTB versus a voltage-controlled oscillator tuning range required for 1 unit interval deskew), the proposed receiver makes them independent. Therefore, the proposed receiver can achieve the optimal JTB in a wide range supporting various applications by controlling deskew phase and JTB independently. A test chip was implemented to prove 11-Gb/s data recovery with constant 70-MHz to 1-GHz JTB in 0.13-mu m CMOS.
