Low-voltage-In-Package-INterCONnect (LIPINCON) is a proprietary system interconnect architecture that facilitates data transmission across all linked components.
Overview[edit]
LIPINCON is an interconnect architecture designed for chiplet designs with advanced packaging technologies such as InFO and CoWoS. LIPINCON uses a timing compensation mechanism in order to achieve a low-power and small area slave PHY (e.g., memory die or a transceiver die) while excluding the PLL/DLL but retaining good timing margins.
Architecture[edit]
The architecture is designed to take advantage of an advanced packaging technology such as CoWoS whereby multiple dies are stacked on a silicon interposer communicating by PHYs over short wires. LIPINCON uses two different types of PHYs: PHYC for an SoC die and PHYM for a memory, transceiver, or similar kind of dies. The clock source in the PHYM relies on one system clock propagated from PHYC. There is no PLL/DLL function blocks built in PHYM because it assumes that the SoC will generally be fabricated on a more advanced node and is therefore capable of handling this more efficiently than a memory/transceiver that may be made on a more mature node.
