Transceivers accelerate backplane signalling
Fairchild Semiconductor has released the industry's first 1 and 2bit Gunning Transceiver Logic Plus (GTLP) transceivers in 8-lead packaging
The GTLP1B151, GTLP2T152 and GTLP1B153 are packaged in 8-lead SOIC and 8-pin US8. These devices are designed to drive data and control signals across medium and heavily loaded backplanes. All three devices can operate with ASIC, FPGA and microprocessor GTL and GTL+ I/O. These devices are ideal for applications including server, wireless, and wired communication applications.

Low-voltage dual-supply voltage translator increases design flexibility by allowing designers to control the direction of each bit individually
The GTLP1B151 is a 1bit transceiver with separate LVTTL inputs and outputs that enable better interfacing with many control pins on ASICs, FPGAs and microprocessors.
The transceiver's optional feedback path can be used to sense data or to provide diagnostics.
The GTLP2T152 is a 2-bit transceiver and the GTLP1B153 is a 1bit dedicated driver/receiver pair.
All devices operate at 3.3V and provides bi-directional LVTTL-to-GTLP signal-level translation, a 1.0V output swing, 100mV threshold voltage (VTH), and +/-50mA drive (IOL/IOH) for backplane driving.
Additional features include bushold, edge-rate control and high-impedance power up/down and off.
Bushold eliminates the need for external resistors by offering a known state on device inputs.
GTLP's optimised edge-rate control reduces bus settling time and EMI.
High impedance power up/down/off supports live insertion into active backplane environments.
GTLP is a derivative of Gunning Transceiver Logic (GTL), a JESD8-2 JEDEC standard.
These devices are designed using Fairchild's advanced BiCMOS process and are process, voltage and temperature (PVT) compensated.
1000-piece quantities in the 8-lead SOIC package are available now and US8 package.
will be available in November.
Fairchild's EnSignaTM Lab and EnSigna web support system design, simulation, and evaluation for these devices and other ICs used in backplane and intraconnect applications.
