0.18 µm SONET OC3-OC12 622 MSps SerDes The Challenge Our customer required a multiple data-rate SerDes PHY development within a very tight time schedule. AnSem was contacted late into the project, making a demanding “get it right the first time” approach an absolute must.  Our challenge was to make this complex SerDes development a reality and to push our already extensive SerDes experience into a very short development cycle without compromising on robustness or performance. The solution AnSem used its expertise and existing IP blocks to generate a block within the given strict time constraints. Intelligent porting of the various building block architectures was used to obtain the required current and speed constraints. Result for the customer The project went into production after first silicon, allowing the customer to capture his market window.
