Texas Instruments has introduced the 1.6 Gb/s to 2.7 Gb/s serializer/deserializer. The device, its TLK2711HFGQMLV, is a member of the WizardLink family of multi-gigabit transceivers. It is qualified to MIL-PRF-38535 (QML) Class V and was designed to support serial interfaces in high-speed, data-bus applications in aerospace equipment, including satellites.
Ideal for high-speed backplane and point-to-point data links, the TLK2711HFGQMLV provides very high-speed (2.5 Gb/s) I/O data channels for baseband data transmission over a controlled-impedance medium of approximately 50 Ohms. The transmission media can be a printed circuit board, copper conductors or fiber-optic cable. With a 2.5 V-power supply and drawing less than 500 mW, the device is said to offer a lower power solution than other parallel-data transmission architectures.
The TLK2711HFGQMLV 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 is fed into the transmitter and is then delivered to the receiver over a serial channel, which can be coax, a controlled-impedance backplane or an optical link. The data is then reconstructed into its original parallel format.
The TLK2711HFGQMLV is offered in a high-performance, 68-lead ceramic quad flat package (HFG). Currently, the TLK2711HFGQMLV is a convenience part number and the device may be ordered to a DSCC SMD part number (5962-0522101VXC) with radiation data available. Samples are available and order entry is open; initial production units are expected to ship in October.
