This paper presents a new methodology for developing a performance-driven OTN VRM specification. OTN applications have special requirements of maintaining very low noise in low-to-mid frequency range. PLL and transmitter jitter performance is evaluated including three noise sources from device, PDN, and VRM of all power supplies. As an outcome, OTN VRM noise mask is generated by sweeping VRM noise magnitude and frequency for given OTN jitter specification. Example solutions are provided to meet the resultant OTN VRM specifications. The proposed methodology also utilizes a newly-developed accurate on-chip modeling technique which is frequency-dependent and highly distributed.

Takeaway

Transceiver OTN applications are especially sensitive to noise in low-to-mid frequency range. This necessitates new special VRM specifications that facilitate OTN system design. New methodology for performance-driven OTN VRM specifications is developed. New approach to generate the worst-case OTN PDN noise profiles using newly-developed on-chip modeling technique is also discussed.
