Voltage controlled oscillators for 40Gbit/s cascaded bit-interleaving PON

Technologies such as the Internet-of-Things and cloud services demand dynamic bandwidth allocation flexibility, which is not offered by the currently deployed solutions. The Bit-Interleaving PON (BiPON) and its cascaded extension the Cascaded Bit-Interleaving PON (CBI-PON) offer a solution that allows to increase bandwidths, reduce power consumption and have a much more flexible dynamic bandwidth allocation scheme. CBI-PON consists of multiple levels of BiPON with different line rates. For each of these line rates, clock-and-data recovery must be performed, which requires a set of different Voltage Controlled Oscillators (VCOs). This paper presents the VCOs designed for the CABINET chip, an implementation of a CBI-PON network device, allowing clock-and-data recovery for 40Gbit/s, 10 Gbit/s and 2.5 Gbit/s line rates.
