TLK10031CTR

Interface - Drivers, Receivers, Transceivers

TLK10031CTR is a highly integrated non-blocking Gigabit-rate serializer/deserializer (Serializer/Deserializer) used for high-speed data transmission over twisted-pair cable. It is designed to meet the IEEE 802.3z standard and supports 1000BASE-T Ethernet, FibreChannel over Cat5, and proprietary high-speed signals with data rates up to 1 Gbps over long distances of Category 5 unshielded twisted-pair (UTP) cable. This device is designed for use in a wide range of data communication equipment, such as optical network and network adapters, embedded applications, PONs (Passive Optical Networks), storage networking, and original equipment manufacturers (OEM).

Application Field

TLK10031CTR is a highly versatile device capable of providing reliable and low power consumption Gigabit-rate communication over Category 5 UTP. The serializer/deserializer (SerDes) supports both 802.3z and proprietary high-speed protocols such as FibreChannel over Cat5, 1000BASE-T Ethernet, and 10GBASE-T Ethernet. It is also suited for applications that require reliable high speed transmission over unshielded twisted-pair (UTP) cables, including optical networks and Ethernet adapters, storage networking, embedded systems, and Passive Optical Networks (PONs).

Working Principle

The TLK10031CTR Transceiver is designed for low power consumption and can operate at a data rate of up to 1 Gbps over long distances of Cat 5 UTP cable. It has a fully differential signal path, which provides the low-loss and low-noise performance required for demanding 1000Base-T applications. The transmitter incorporates an Adaptive DSP Equalizer, which is used to compensate for the effects of dispersion and cross-talk in the UTP link. The equalizer is optimized to provide equalization up to 20 MHz. The local serial loopback function is used to verify the performance of the SerDes and allows rate adaptation to different cable lengths.

The receive path of the transceiver contains decision feedback equalization (DFE), which provides improved SNR by minimizing ISI (Inter Symbol Interference). The receiver also includes adaptive clock recovery. This ensures the highly reliable data recovery even in harsh environments. It also incorporates many features such as low frequency jitter tolerance to reduce EMI (Electromagnetic Interference) for better system operation and data integrity.
