General Description


The SCAN12100 is a 1228.8 and 614.4 Mbps serializer/deseralizer (SerDes) for high-speed bidirectional serial data transmission over FR-4 printed circuit board backplanes, balanced cables, and optical fiber. The SCAN12100 integrates precision delay calibration measurement (DCM) circuitry that measures link delay components to better than ± 800 ps accuracy.

The SCAN12100 features independent transmit and receive PLLs, on-chip oscillator, and intelligent clock management circuitry to automatically perform remote radio head synchronization and reduce the cost and complexity of external clock networks.

The SCAN12100 is programmable though an MDIO interface as well as through pins, featuring configurable transmitter de-emphasis, receiver equalization, speed rate selection, internal pattern generation/verification, and loop back modes. In addition to at-speed BIST, the SCAN12100 includes IEEE 1149.1 and 1149.6 testability.
