1.6 To 2.7 GBPS Transceiver

The TLK2711 is a member of the WizardLink transceiver family of multigigabit transceivers, intended for use in ultrahigh-speed bidirectional point-to-point data transmission systems. The TLK2711 supports an effective serial Interface speed of 1.6 Gbps to 2.7 Gbps, providing up to 2.16 Gbps of data bandwidth.
The primary application of this chip is to provide very high-speed I/O data channels for point-to-point baseband data transmission over controlled impedance media of approximately 50 . The transmission media CAN be printed-circuit board, copper cables, or fiber-optic cable. The maximum rate and distance of data transfer is dependent upon the attenuation characteristics of the media and the noise coupling to the environment.
This 1283 device CAN also be used to replace parallel data transmission architectures by providing a reduction in the number of traces, connector terminals, and transmit/receive terminals. Parallel data loaded into the transmitter is delivered to the receiver over a serial channel, which CAN be a coaxial copper cable, a controlled impedance Backplane or an optical link. It is then reconstructed into its original parallel format. It offers significant power and cost savings over parallel solutions, as well as scalability for higher data rates in the future.
The TLK2711 performs Data Conversion parallel-to-serial and serial-to-parallel. The Clock extraction functions as a physical layer Interface device. The serial transceiver Interface operates at a maximum speed of 2.7 Gbps. The transmitter Latches 16-bit parallel data at a rate based on the supplied reference Clock (TXCLK). The 16-bit parallel data is internally encoded into 20 bits using an 8-bit/10-bit (8b/10b) encoding format. The resulting 20-bit word is then transmitted differentially at 20 times the reference Clock (TXCLK) rate. The receiver section performs the serial-to-parallel conversion on the input data, synchronizing the resulting 20-bit wide parallel data to the recovered Clock (RXCLK). It then decodes the 20-bit wide data using the 8-bit/10-bit decoding format resulting in 16 bits of parallel data at the receive data terminals (RXD0-15). The outcome is an effective data payload of 2 Gbps to 2.5 Gbps (16 bits data x the frequency).
The TLK2711 is provided in two packages options: a 80-pin ball grid array MicroStar Junior package and a 64-pin VQFP (RCP) package.
The TLK2711 provides an internal loopback capability for self-test purposes. Serial data from the serializer is passed directly to the deserializer, providing the protocol device with a functional self-check of the physical Interface
The TLK2711 has a loss of signal (LOS) detection circuit for conditions where the incoming signal no longer has a sufficient voltage amplitude to keep the Clock recovery circuit in lock.
The TLK2711 allows users to implement redundant ports by connecting receive data bus terminals from two TLK2711 devices together. Asserting the LCKREFN to a low state will cause the receive data bus terminals, RXD[0:15], RXCLK, RKLSB, and RKMSB to go to a high-impedance state. This places the device in a transmit-only mode since the receiver is not tracking the data.
The TLK2711 uses a 2.5-V supply. The I/O section is 3 V compatible. With the 2.5-V supply the chipset is very power efficient, consuming less than 450 mW typically. The TLK2711 is characterized for operation from 40C to 85C (RCP only).
The TLK2711 is designed to be hot-plug capable. An on-chip power-on reset circuit holds the RXCLK low and goes to high impedance on the parallel side output signal terminals as well as TXP and TXN during power up.
