Description

The STLVD111 is a low skew programmable 1 to 10 differential LVDS driver, designed for clock distribution. The select signal is fanned out to 10 identical differential outputs.

The STLVD111 is provided with a 11 bit shift register with a serial in and a Control Register. The purpose is to enable or power off each output clock channel and to select the clock input.

The STLVD111 is specifically designed, modelled and produced with low skew as the key goal. Optimal design and layout serve to minimize gate to gate skew within a device. The net result is a dependable guaranteed low skew device.

The STLVD111 can be used for high performance clock distribution in 2.5V systems with LVDS levels. Designers can take advantage of the device’s performance to distribute low skew clocks across the backplane or the board.
