Function:
Auto-Mute (Bit 7)
Interpolation Filter Select (Bit 6)
De-Emphasis Control (Bits 5:4)
When set, enables the Auto-Mute function. See “Auto-Mute” on page 30.
This Function allows the user to select whether the Interpolation Filter has a fast or slow roll off. When
set, this bit selects the slow roll off filter, when cleared it selects the fast roll off filter. The - 3 dB corner
is approximately the same for both filters, but the slope of the roll off is greater for the fast roll off filter.
Implementation of the standard 50/15 µs digital de-emphasis filter response, Figure 19, requires re-
configuration of the digital filter to maintain the proper filter response for 32, 44.1 or 48 kHz sample
rates. NOTE: De-emphasis is available only in Single-Speed Mode. See Table 13 below.
