Preliminary specification
LIne MEmory noise Reduction IC (LIMERIC)
FEATURES • 2-D adaptive vertically recursive noise reduction • Noise reduction for Y, U and V signals in 4 : 1 : 1 format • Single 5 V ±10% power supply • Communication by means of serial communication protocol 83C654 (SNERT bus) • Via SNERT bus, 10 different types of noise reduction selectable; the noise reduction function can also be disabled • Phase relation write enable input/output signal simultaneously switchable over one clock period w.r.t.
