Frequently Asked Questions
What signal density and pitch does the SEAF-20-05.0-STL-05-2-A-K-TR provide?
The SEAF-20-05.0-STL-05-2-A-K-TR provides 100 positions at a 0.050" (1.27 mm) pitch in an open-pin-field array format, delivering high signal density in a compact footprint. This pitch and position count supports FPGA and ASIC mezzanine boards with extensive I/O requirements in a minimal board area.
What data rates can the SEARAY SEAF-20-05.0-STL-05-2-A-K-TR support?
The SAMTEC SEARAY connector family is characterized to support multi-gigabit data rates, with the controlled-impedance open-pin-field design enabling signal integrity at rates above 5 Gbps per differential pair. This makes the SEAF-20-05.0-STL-05-2-A-K-TR suitable for PCIe, JESD204B, and other high-speed protocols used in communications and instrumentation hardware.
How does the open-pin-field design of the SEAF-20-05.0-STL-05-2-A-K-TR benefit FPGA mezzanine designs?
Open-pin-field arrays allow engineers to assign any of the 100 positions at 0.050" pitch as differential pairs, single-ended signals, power, or ground without fixed lane constraints. This flexibility reduces PCB trace routing complexity on FPGA carrier boards and allows signal grouping to be optimized for each design, compared to fixed-lane mezzanine connectors that impose rigid differential pair placement across the 100-position array.
