5 Retimer and Redrivers Part Selection

Table 5-1 provides a summary of TI's portfolio of signal conditioning devices aimed at 25Gbps to 28Gbps system applications. TI's signal conditioning portfolio spans both retimer and redriver product types. TI's devices are suitable for use in systems spanning a wide range of applications requiring chip-to-chip channel reach extension, from Ethernet data center switches to telecommunications routers and CPRI equipment. Table 4 lists multiple features for each part number including channel count, package type and electrical performance parameters. TI's portfolio has the following differentiating features worth highlighting:

• TI's 25G/28G product family includes 2-channel, 4-channel and 8-channel signal conditioning devices, allowing the system developer to chose a device that optimizes their system board area and layout.
• TI's eight channel retimers and redrivers are fully pin-to-pin and footprint compatible. This 8-channel BGA footprint thus provides the ultimate flexibility for system developers, as they can chose to populate with either the retimer or the redriver based on the needs of specific sections of their board.
