NIPPON PRECISION CIRCUITS—13
Deemphasis Filter (DEEM)
The built-in digital deemphasis filter is designed to
operate at 44.1 kHz. Deemphasis is ON when DEEM
is HIGH, and OFF when DEEM is LOW.
Attenuation (MODE, ATCK, MLEN)
The digital attenuation mode is selected when
MODE is LOW. The attenuator operates by
multiplying the internal 6-bit up/down counter’s
output data with the signal data.
The direction of the 6-bit up/down counter is
controlled by the level on MUTE (down when
MUTE is HIGH, and up when MUTE is LOW). The
count is advanced on the rising edge of ATCK.
When the count reaches 0 (down) or 63 (up), the
counter automatically stops.
The gain is set by the counter contents DATT as
follows.
Upon system initialization or when MODE changes
state, DATT is set to 63, which corresponds to the
maximum gain of 0 dB as shown in table 2.
