The TLK10002 device is a dual-channel, multi-rate transceiver intended for use in high-speed bidirectional point-to-point data transmission systems. It has special support for the wireless base station Remote Radio Head (RRH) application, but may also be used in other high-speed applications. It supports all the CPRI and OBSAI rates from 1.2288 Gbps to 9.8304 Gbps.

The TLK10002 performs 1:1, 2:1 and 4:1 serialization of the 8B/10B encoded data streams presented on its low-speed (LS) side data inputs. The serialized 8B/10B encoded data is presented on the high-speed (HS) side outputs. Likewise, the TLK10002 performs 1:1, 1:2 and 1:4 deserialization of 8B/10B encoded data streams presented on its high-speed side data inputs. The deserialized 8B/10B encoded data is presented on the low-speed side outputs. Depending on the serialization or deserialization ratio, the low-speed side data rate can range from 0.5 Gbps to 5 Gbps and the high-speed side data rate can range from 1 Gbps to 10 Gbps. Both low-speed and high-speed side data inputs and outputs are of differential current mode logic (CML) type with integrated termination resistors. In the 1:1 mode, the input can be raw (non-8B/10B encoded) data, allowing for transmission of PRBS data through the device.

The TLK10002 performs data serialization or deserialization and clock extraction as a physical layer interface device. Flexible clocking schemes are provided to support various operations. They include the support for clocking with an externally-jitter-cleaned clock recovered from the high-speed side.Read more
