When le is high, 6-bit data in the serial input register is transferred to the attenuator. When le is high ClK is masked to prevent data transition during output loading. for all modes of operations, gain will remain constant while le is kept low. 12 Variable gain amplifiers - digital - smt 12 - 6 Truth Table parameter min. serial period, tsCK Control set-up time, tCs Control hold-time, tCH le setup-time, tln min. le pulse width, tleW min le pulse spacing, tles serial clock hold-time from le, tCKn Hold time, tpH. latch enable minimum Width, tlen setup time, tps typ. 100 ns 20 ns 20 ns 10 ns 10 ns 630 ns 10 ns 0 ns 10 ns 2 ns b5 16 db High High High High High High low low b4 8db High High High High High low High low serial Word b3 4 db High High High High low High High low b2 2 db High High High low High High High low b1 1 db High High low High High High High low b0 0.5 db High low High High High High High low relative gain setting reference 0 db -0.5 db -1 db -2 db -4 db -8 db -16 db -31.5 db any combination of the above states will provide a relative gain setting approximately equal to the sum of the bits selected.
