### **Descriptions:**
- The **ISPGDX120A-5T176** is a high-performance, field-programmable digital crosspoint switch designed for signal routing and switching applications.  
- It provides flexible, non-blocking signal routing with low latency and high-speed performance.  
- Suitable for applications requiring dynamic signal switching, such as telecommunications, networking, and data processing.  

### **Features:**
- **Non-Blocking Switch Matrix:** Allows any input to connect to any output without blocking.  
- **Low Latency:** Pin-to-pin delays as low as 5ns.  
- **In-System Programmability (ISP):** Supports reprogramming via JTAG interface.  
- **High-Speed I/O:** Supports data rates up to 200 MHz.  
- **On-Chip Memory:** Includes distributed RAM for configuration storage.  
- **Flexible I/O Options:** Supports both registered and combinatorial signal paths.  
- **Low Power Consumption:** Optimized for 3.3V operation.  
- **Wide Applications:** Used in telecom switches, test equipment, and signal processing systems.  

This device is part of Lattice's **GDX** (Generic Digital Crosspoint) family, designed for high-speed signal routing and switching applications.

Application Scenarios & Design Considerations

In-System Programmable Generic Digital CrosspointTM

Alternative Part Number

  • LC4256V-5T176C --: Lattice ispMACH 4000V CPLD in the same 176-pin TQFP package with comparable 256-macrocell logic capacity and 5 ns speed grade, suitable as a functional replacement for the ispGDX120A crosspoint switch in many designs.
  • EPM3256AQC208-5 --: Altera MAX 3000A CPLD with 256 macrocells and 5 ns speed grade; a widely available alternative CPLD family that can implement equivalent crosspoint/switch logic, though the package is 208-pin PQFP so a board redesign is required.
  • XC95288XL-5TQ144C --: Xilinx XC9500XL CPLD with 288 macrocells and 5 ns speed grade, offering similar programmable logic density and fast pin-to-pin performance as a fallback replacement, requiring package adaptation from the original 176-pin TQFP.
