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 causes the receive data bus terminals
(RXD0–RXD15, 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 I/Os are 3-V compatible. The TLK2711 is characterized for operation from –55°C to 125°C Tcase.
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.
