AMD XC5VLX155T-2FF1738C

Overview

XC5VLX155T-2FF1738C from AMD (formerly Xilinx) is a high-performance Virtex-5 FPGA featuring 155,328 logic cells, 12.5 Mb of block RAM, and 640 DSP48E slices. It supports PCIe Gen1 x8, DDR2-533 memory interfaces, and operates at -2 speed grade with 1.0V core voltage. It is used in high-bandwidth digital signal processing systems such as radar baseband processing.

For engineers reviewing the XC5VLX155T-2FF1738C datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (720 user I/Os), transceiver line rate (3.2 Gbps), thermal design power (14.9 W), and package compatibility with FF1738 flip-chip BGA.

Technical Context

The XC5VLX155T-2FF1738C implements a hierarchical FPGA architecture with configurable logic blocks (CLBs), dedicated DSP slices, and integrated multi-gigabit transceivers (MGTs). It includes 24 RocketIO GTP transceivers supporting serial protocols including SATA, Serial RapidIO, and CPRI.

Its clocking system comprises eight DCMs and two PLLs for low-jitter clock synthesis and phase alignment across multiple domains. The device targets high-reliability embedded computing where deterministic timing closure and multi-voltage I/O banks (1.2V to 3.3V) are required.

FAQ

What is the maximum supported I/O standard for XC5VLX155T-2FF1738C?

The XC5VLX155T-2FF1738C supports LVDS, SSTL-18/25, HSTL-I/II, and differential LVPECL across its 22 I/O banks. Each bank is independently configurable for voltage levels from 1.2 V to 3.3 V, enabling direct interfacing with DDR2 memory, ADCs, DACs, and optical modules without level-shifting components.

Does XC5VLX155T-2FF1738C include built-in PCIe functionality?

Yes, the XC5VLX155T-2FF1738C integrates a hard PCIe Endpoint block compliant with PCI Express Base Specification 1.1. It supports x1, x2, x4, and x8 link widths at 2.5 Gbps per lane, with dedicated DMA and TLP handling logic - eliminating the need for external PCIe switch or bridge ICs in endpoint applications.

What is the operating temperature range for XC5VLX155T-2FF1738C?

The XC5VLX155T-2FF1738C is rated for the commercial temperature range of 0°C to +85°C (case temperature). This rating applies to the -2 speed grade variant and is validated per Xilinx DS100 specification; derating is required above 70°C ambient for sustained TDP operation.

How many RocketIO transceivers does XC5VLX155T-2FF1738C have?

The XC5VLX155T-2FF1738C includes 24 RocketIO GTP transceivers. Each supports serial data rates from 100 Mbps to 3.2 Gbps and protocols including SATA, Serial RapidIO, CPRI, and XAUI - with programmable pre-emphasis and receiver equalization for channel loss compensation.

Is partial reconfiguration supported on XC5VLX155T-2FF1738C?

Yes, the XC5VLX155T-2FF1738C supports partial reconfiguration via Xilinx ISE Design Suite 14.7 and later. This capability allows dynamic swapping of logic modules - such as filter coefficients or modulation schemes - while maintaining system operation, which is essential for adaptive radar and software-defined radio platforms.
