FAQ

What is the maximum operating frequency of the TMS320DM648ZUTD9?

The TMS320DM648ZUTD9 is rated for a maximum operating frequency of 900 MHz, corresponding to a 1.11 ns instruction cycle time. This speed grade is validated across the full industrial temperature range (–40°C to +105°C) and supports 8000 million instructions per second (MIPS) under typical conditions. The device's PLL1 controller accepts a 27-MHz crystal input and generates the internal SYSCLK using programmable multipliers (PLLM = 15–31). Performance-critical applications must observe setup/hold timing for DDR2 and SGMII interfaces at this clock rate.

Does the TMS320DM648ZUTD9 support dual SGMII Ethernet interfaces?

Yes, the TMS320DM648ZUTD9 integrates a 3-port Ethernet switch subsystem with two independent SGMII interfaces (SGMII0 and SGMII1), enabling simultaneous 1-Gbps connections to two external PHYs. This differs from the DM647 variant, which provides only one SGMII port. Each SGMII link operates at 1.25 Gbps with embedded 8b/10b encoding and supports IEEE 802.3z compliance. The MDIO module manages both PHYs through a shared management bus, allowing coordinated configuration and status monitoring.

What is the L2 memory size and configuration capability of the TMS320DM648ZUTD9?

The TMS320DM648ZUTD9 features 512 KB (4 M-bit) of unified L2 memory that can be flexibly allocated as mapped RAM, cache, or a combination thereof. Unlike the DM647's 256 KB L2, this doubled capacity supports larger frame buffers for multi-channel video, faster code execution from L2 cache, and efficient scratch-pad usage for real-time DSP kernels. Configuration is controlled via L2CFG and L2ALLOC registers; software can dynamically partition regions for cache coherency or lock critical data in non-cacheable mapped RAM.

Which video standards are supported by the TMS320DM648ZUTD9 video ports?

The TMS320DM648ZUTD9's five 16-bit video ports support CCIR601, ITU-BT.656, BT.1120, SMPTE 125M, 260M, 274M, and 296M standards. Each port operates in programmable capture or display mode, with dual-channel A/B buffers (5120 bytes total per port) and hardware handshaking for frame synchronization. These capabilities enable glueless interfacing to common video decoders (e.g., TVP5158) and encoders (e.g., THS8200), eliminating external FIFOs or logic for standard-definition and high-definition video streams.

What package type and thermal specifications apply to the TMS320DM648ZUTD9?

The TMS320DM648ZUTD9 uses a 529-pin nFBGA package (suffix ZUT), measuring 19 mm × 19 mm with 0.8 mm ball pitch and a thermal pad on the underside. It is qualified for industrial temperature operation (–40°C to +105°C) and employs a 0.09-μm/6-level Cu metal CMOS process. Thermal resistance (θ_JA) is 21.5°C/W under JEDEC JESD51-2 conditions; recommended PCB layout includes solid ground/power planes and ≥6 thermal vias under the thermal pad to maintain junction temperature within limits during sustained 900-MHz operation.
