The **ASP-2141-R** is a high-performance, precision-engineered electronic component commonly used in high-speed digital systems. It is part of the **VITA 42 XMC** (Switched Mezzanine Card) standard connector family, specifically manufactured by **Samtec**. --- ### 1. Key Technical Specifications The ASP-2141-R is a high-density, multi-pin connector designed for board-to-board applications where reliability and signal integrity are critical. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Samtec | | **Connector Type** | XMC Male (Plug/Terminal) | | **Pin Count** | 114 Pins (6 rows of 19) | | **Pitch** | 1.14 mm x 1.14 mm | | **Termination** | Solder Charge (BGA style) | | **Standard Compliance** | VITA 42 (XMC) | | **Mating Style** | Mezzanine (Stacking) | --- ### 2. Functional Electronic Characteristics #### A. Signal Integrity The ASP-2141-R is designed to handle high-speed differential pairs. It supports protocols such as **PCI Express (Gen 2/3)**, **RapidIO**, and **10Gb Ethernet**. The design minimizes crosstalk and impedance mismatch. #### B. The Solder Charge Technology Unlike traditional through-hole pins, the "R" suffix often denotes the use of Samtec’s **Solder Charge** technology. * **Mechanism:** Small spheres of solder are pre-attached to the leads. * **Benefit:** This allows for high-yield surface mount (SMT) reflow soldering, ensuring a robust mechanical and electrical connection even with high pin densities. #### C. Power and Grounding The 114-pin layout is typically mapped to provide a mix of: * **Differential Data Lanes:** For high-speed data transfer. * **Power Rails:** Supporting 3.3V, 5V, and 12V inputs. * **System Management:** Dedicated pins for JTAG and I2C/SMBus communication. --- ### 3. Common Applications The ASP-2141-R is primarily found in ruggedized and industrial computing environments: 1. **Defense & Aerospace:** Connecting FPGA mezzanine cards to baseboards in VPX systems. 2. **High-Performance Computing (HPC):** Data acquisition boards and signal processing units. 3. **Telecommunications:** Network switches and high-speed routing hardware. --- ### 4. Mating Compatibility The ASP-2141-R (Male) typically mates with the **ASP-2144-R** (Female) or similar VITA 42 compliant sockets. The stack height (the distance between the two PCBs) is determined by the specific combination of the plug and receptacle used.
