SCAN12100
1228.8 and 614.4 Mbps CPRI SerDes with Auto RE Sync and
Precision Delay Calibration Measurement
General Description
The SCAN12100 is a 1228.8 and 614.4 Mbps serializer/de-
seralizer (SerDes) for high-speed bidirectional serial data
transmission over FR-4 printed circuit board backplanes, bal-
anced cables, and optical fiber. The SCAN12100 integrates
precision delay calibration measurement (DCM) circuitry that
measures link delay components to better than ± 800 ps ac-
curacy.
The SCAN12100 features independent transmit and receive
PLLs, on-chip oscillator, and intelligent clock management
circuitry to automatically perform remote radio head synchro-
nization 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, inter-
nal pattern generation/verification, and loop back modes. In
addition to at-speed BIST, the SCAN12100 includes IEEE
1149.1 and 1149.6 testability.
