摘要
作者采用D-FF触发器、鉴相器和VCO构成的锁相环,研制出了码率为10.709 Gbit/s的时钟数据再生模块.该模块的中心工作码率可在9.5~11 Gbit/s之间设定,锁定带宽Δf≈110MHz,输入信号幅度VINp-p80~1600mV,输出信号幅度VD-p-p≈900mV,输出信号抖动均方根值JD-RMS≈1.5~1.6ps、抖动峰峰值JD-p-p≈7~8ps.
Using a D-FF, phase comparator and VCO, the authors produced a 10.709 Gbit/s CDR based on PLL. The operating frequency of the CDR can be set within 9.5 - 11GHz,the lock bandwidth △f is about 110 MHz, the amplitude of input signal VINP-P is 80 - 1600mV,the amplitude of output data VD-P-P is about 900mV,the jitter RMS of output data JD-p-p is 1.5 - 1.6ps and the peak-to-peak jitter of output data JD-P-P is 7 - 8ps.
