i705 x general description the i7050/i7051 limiting amplifiers, with complementary pecl data outputs, are designed for fiber - optic based communication with data rate up to 200 mbps. each device includes a programmable signal - level detector, allowing the u ser to set the thr eshold level at which pecl data outputs are enabled. the hysteresis is fixed internally in 2db optical to prevent chattering when t he signal level is close to the threshold level. the i7050's signal detect outputs are compatible with pecl - logic levels. the i7051 has cmos signal detect outputs. stb and jam can be used to implement a squelch function, which gives fixed logic levels at data o utputs when the input signal is below the programmed threshold level. features ? program mable chat ter - free signal level detector. ? 1.6 mv input sensitivity (differential). ? 3.3v to 5v supply voltage. ? pecl data outputs. ? pecl signal detect logic interface (i7050). ? cmos signal detect logic interface (i7051). ? available in ssop - 16 package.
