• Clock Management  Device-level clock resources include up to ten PLLs and two DLLs to support complex clocking and multi-rate designs (per family datasheet).
• Package and Mounting  484-BBGA package case, supplier device package 484-FPBGA (23×23 mm), surface-mount type for compact board-level integration.
• Power and Temperature  Voltage supply range 1.14 V to 1.26 V with operating temperature 0 °C to 85 °C; commercial-grade device.
• Compliance  RoHS compliant.

Typical Applications

• High-speed serial connectivity  SERDES channels and extensive I/O make the device suitable for implementing PCIe, Ethernet, SONET/SDH or other serial links at multi-gigabit rates (family-level interfaces supported).
• Real-time signal processing  sysDSP architecture and 18×18 multipliers enable DSP tasks such as filtering, FFT stages, and accelerated numeric processing in communications and video systems.
• Embedded system control  Large logic capacity and abundant I/O support complex control, protocol handling, and glue-logic tasks in industrial and commercial embedded platforms.
• Memory-intensive buffering  Approximately 4.53 Mbits of on-chip RAM supports deep buffering and packet/stream storage for network and streaming applications.

Unique Advantages

• High integration density: Combining ~92,000 logic elements with ~4.53 Mbits of RAM and 295 I/Os reduces external component count and simplifies system BOM.
• Multi-protocol serial support: On-package SERDES capability (4 channels) and family-level support for up to 3.2 Gbps data rates enable flexible high-speed link implementation.
• DSP-ready fabric: sysDSP slices and 128 18×18 multipliers provide a hardware-accelerated path for compute-heavy signal processing tasks.
• Robust clocking resources: Multiple PLLs and DLLs afford flexible clock domain management for mixed-rate, multi-interface systems.
• Compact, board-friendly package: 484-FPBGA (23×23 mm) surface-mount package balances pin density and board footprint for space-constrained designs.
• Commercial-grade, RoHS compliant: Suited for mainstream embedded applications with environmental compliance for lead-free assembly.
