Functional Differences Between Rev. 1.0 and Rev. 1.1 of the MSC8157 DSP Family
Engineering bulletin detailing functional differences and errata fixes between Rev 1.0 and 1.1 of Freescale MSC8157 and MSC8158 multicore DSPs.
Overview
This engineering bulletin outlines the functional differences between silicon revisions 1.0 and 1.1 for the MSC8157 DSP family, which includes the MSC8157, MSC8157E, MSC8158, and MSC8158E. It specifies changes to Device IDs across SPRIDR, RapidIO, and JTAG registers to identify the newer silicon. The document highlights three critical SerDes errata fixed in Rev 1.1: SERDES1 (PLL instability), SERDES2 (3.125 Gbaud operation enablement), and SERDES4 (SGMII and Serial RapidIO 1.25 Gbaud communication enablement).
Use Cases
- Identifying silicon revision versions via Device ID and JTAG registers.
- Troubleshooting SerDes PLL instability or lock issues in older hardware revisions.
- Validating high-speed communication support for 3.125 Gbaud SerDes ports.
- Reviewing hardware errata fixes during system migration from Rev 1.0 to Rev 1.1 silicon.
