Key Features
- 20-position dual-row Q Strip header with integrated ground plane delivers controlled impedance for signals exceeding 25 Gbps per lane
- 0.80 mm pitch high-speed design minimizes stub length and crosstalk in dense differential pair routing applications
- STL (straddle-mount) termination style allows the connector to mount on the PCB edge, saving significant board real estate in slim form-factor designs
Applications
The QTE-020-02-STL-D is designed for high-speed digital interfaces such as PCIe, JESD204, and LVDS in FPGA evaluation boards, RF modules, and high-bandwidth data acquisition systems operating at multi-Gbps data rates. Its 0.80 mm pitch and ground plane construction suit designs where signal integrity between mezzanine cards and host boards is paramount. It is commonly found in wireless infrastructure equipment and advanced test instrumentation requiring 20-pin high-frequency edge connections.

Frequently Asked Questions
What data rate can the QTE-020-02-STL-D reliably support in a differential pair configuration?
The QTE-020-02-STL-D supports differential data rates exceeding 25 Gbps per lane due to its integrated ground plane and controlled-impedance construction. The 0.80 mm pitch limits stub length, reducing insertion loss and cross-talk for PCIe Gen 3/4 or JESD204B interface applications.
What does the STL termination style mean for PCB layout of the QTE-020-02-STL-D?
The STL (straddle-mount) style means the connector straddles the PCB edge, with contacts on both sides of the board. This places the 20-pin dual-row header at the board perimeter, eliminating the need for routing signal traces to an interior zone and reducing total PCB area by several hundred square millimeters in compact mezzanine designs.
When would an engineer choose the QTE-020-02-STL-D over a standard 0.100" pitch header for a mezzanine card?
Engineers select the QTE-020-02-STL-D when the design must carry signals at 10 Gbps or higher because a standard 2.54 mm pitch header lacks controlled impedance and ground return paths adequate for those frequencies. The 0.80 mm pitch Q Strip's ground plane maintains 50 ohm or 100 ohm differential impedance across all 20 positions, which standard headers cannot guarantee.
