TMS320C6670
7.14 HyperLink Peripheral
The TMS320C6670 includes the HyperLink for companion chip/die interfaces. This is a four-lane SerDes interface
designed to operate up to 12.5 Gbps per lane from pin-to-pin. The interface is used to connect with external
accelerators that are manufactured using TI libraries. The Hyperbridge links must be connected with DC coupling.
The interface includes the serial station management interfaces used to send power management and flow messages
between devices. This consists of four LVCMOS inputs and four LVCMOS outputs configured as two 2-wire output
buses and two 2-wire input buses. Each 2-wire bus includes a data signal and a clock signal.
