Abstract
A 5GHz Gated VCO for burst-mode operation in 10Gbps GPON and EPON systems is presented. The GVCO consists of four stages of XNOR/XOR cell with voltage-controlled delays, and aligns output clock to burst data within 2 bits time. The GVCO has a tuning range from 4.4GHz to 6.2GHz. The phase noise of the GVCO in steady state circuit is -105dBc/Hz at 5MHz offset. The circuit is implemented in SMIC 0.18µm CMOS process, occupies an area of 425*480µm 2. The power consumption is 35mW (with I/O buffers).
