ON Semiconductor has introduced the NBSG111, a 1:10 silicon germanium (SiGe) differential clock driver with reduced swing emitter couple logic (RSECL) outputs that deliver 10 identical signals from a single input. Inputs incorporate internal 50˝ termination resistors (input to VT pad) and accept negative emitter coupled logic (NECL), positive emitter coupled logic (PECL), low-voltage transistor-transistor logic (LVTTL), current mode logic (CML), or low-voltage differential signaling (LVDS).
The device is the newest member of the company's GigaComm family of high-performance logic ICs designed for telecommunications, networking and automated test equipment applications. Operating at a maximum frequency above 6GHz, the NBSG111 performs fast clock distribution duties.
The new clock driver is functionally equivalent to MC100LVEP111 (a 2.5/3.3V 1:10 differential clock driver) but offers significantly improved bandwidth and lower electro-magnetic interference (EMI) performance. Like MC100LVEP111, NBSG111's synchronous-enable feature is used to avoid a runt clock pulse when the device is enabled or disabled-a common occurrence with an asynchronous control.
The use of RSECL provides an output voltage swing of 400mV-as opposed to 800mV in traditional ECL applications-for reduced power consumption. The NBSG111 is offered in a 49-pin flip-chip ball grid array (FCBGA).
