Data buffer has dual multiplexer
Texas Instruments has introduced the industry's first 0- to 4-Gbps data buffer/signal conditioner with a dual multiplexer.
Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
Designers of portable equipments that require lower voltages and space saving packages now have new options in the TL16C550D and the 32-pin QFN package.
The device supports data transfer rates up to 1.5Mbit/s at 5V, 1.25Mbit/s at 3.5V and 1.0Mbit/s at 2.5V, adding even more flexibility.
The TL16C550D also has a Texas Instruments patented auto flow control feature that comprises auto-RTS (request to send) and auto-CTS (clear to send).
With this feature enabled, RTS becomes active as soon as the receiver has room for more data and notifies the sending serial device to eliminate receiver overrun.
The devices include a programmable baud rate generator capable of dividing a reference clock to produce a 16x reference clock for the internal transmitter logic which can also be used for the receiver logic.
The TL16C550D and TL16C550DI accommodate up to 1.5Mbit/s serial rate (24MHz input clock) allowing for a bit time of 667ns (typical character time of 6.7us).
The TL16C550D and TL16C550DI, which are drop in replaceable for TI's popular TL16C550C and TL16C550CI UART, are available now from TI and its authorised distributors in a 48-pin TQFP (PT) package.
Limited samples of a smaller 5 x 5mm 32-pin QFN (RHB) package are also available now, with production release scheduled for early 3Q04.
In addition, the TL16C550DPT is a distinct option for all new designs requiring the TL16C550C's functionality.
Suggested pricing in 1000-piece quantities is $1.95.
