ON Semiconductor has introduced the NBSG16VS 2.5V/3.3V SiGe differential driver/receiver with a variable output swing that can be programmed to provide output amplitudes ranging between 100mVpp to 700mVpp.

Designed specifically for use as a VCSEL laser modulation or variable gain amplifier, the NBSG16VS is claimed by the company to deliver low jitter, improved signal integrity, and a small footprint for 10Gbps data rates.

The 16-pin FCBGA device is suited as a backplane driver/receiver for optical networking and test equipment, and can also be used in fiber-optic modules based on VCSEL laser technology. Both the SiGe technology and FCBGA packaging enables the IC to operate at >12Gbps, providing designers with the added headroom needed for handling 10GbE and OC-192 signals.

A member of the GigaComm product line, the device is compatible with 2.5V to 3.5V system supplies and offers a current drain of <30mA. An analog control pin is used to implement the programmable amplitude swing.

A proprietary AnyLevel input structure provides direct interface to multiple voltage levels including LVDS, PECL, CML, and CMOS, enabling designers to seamlessly interface these varying output voltages to the NBSG16VS' input.

The device has a low jitter performance as a result of ECL design techniques and a rise/fall time of 40ps. Internal 50-ohm input termination resistors are also included to improve signal integrity, impedance control, and eliminate the need for external resistors.

The NBSG16VS is priced at $22.50 per unit in 10,000 unit quantities.
