Description of Operation
1. Digital Filter
The LC78835K and 78835KM perform arithmetic functions as shown in the following block diagrams.
Oversampling
Constructed of twice as many interpolation filters with a cascade connection arrangement using finite-impulse-
response (FIR) filters. When operating in normal-rate mode, data is transferred through a three-stage cascading
process consisting of 43rd-order, 11th-order, and third-order finite impulse response (FIR) filters connected
together to produce an eight-times oversampled signal. When operating in double-rate mode, data is transferred
through a two-stage cascading process consisting of 43rd-order and second-order finite-impulse-response (FIR)
connected filters to give a four-times oversampled signal. For further details concerning filter characteristics, refer
to page 12.
De-emphasis
Digital de-emphasis is performed using a first-order infinite-impulse-response (IIR) filter. Filter supported
sampling frequencies include fs = 32 kHz, 44.1 kHz and 48 kHz (frequencies are all doubled with double-rate
mode).
