CSIX Level 1 IP Core User’s Guide
Interface Timing and Electrical Speci?cations
CSIX Ports
The core’s CSIX ports are characterized to operate at 100MHz. Incoming signals are sampled on the rising edge of
the CSIX input clock. Outgoing signals are clocked on the rising edge of the outgoing CSIX clock. The instantiated
I/O buffers for the CSIX ports are compatible with LVCMOS and HSTL levels. Detailed timing and electrical speci?-
cations are shown in the paragraphs below.
The following ?gure shows a 64-byte payload arriving at the inbound CSIX interface. Note that the frame is actually
72 bytes long with header and vertical parity added.
