6.18.3

Extended post scale range

Post scale is an attenuation by default. When PS48DB is set to 1, a 48-dB offset is applied

to the configured word, so postscale can act as a gain too.

6.18.4

Extended attack rate

The attack rate shown in Table 66 can be extended to provide up to 8 dB/ms attack rate on

both limiters.

Table 77.

Post scale setup

PS48DB

Mode

Postscale value is applied as defined in coefficient RAM

Postscale value is applied with +48-dB offset with respect to the

coefficient RAM value

Table 78.

Limiter1 attack rate is 8 dB/ms

Table 79.

Extended attack rate setup for limiter 2

XAR2

Mode

Limiter2 attack rate is configured using Table 66

Limiter2 attack rate is 8 dB/ms
