Table 3-12. Power-Supply Rejection Ratio (PSRR) Characteristics
Test conditions (unless specified otherwise):
shows CS4399 connections; input test signal held low (all zero data); GNDA = GNDL = GNDCP =
0 V; voltages are with respect to ground; VL = VA = VD = 1.8 V, VP = 3.6 V; When testing PSRR, PCM input test signal held low (all zero data); T
A
=
+25°C; PCM_AMUTE = 0.
