3 Characteristics and Specifications

Table 3-6. Wideband Flatness Mode Analog Output Characteristics 1

Test conditions (unless otherwise specified): Fig. 2-1 shows CS43198 connections; input test signal is a 32-bit, full-scale 997-Hz sine wave (unless

specified otherwise); GNDA = GNDCP = GNDD = 0 V; voltages are with respect to ground; ASP_M/Sb = 1; typical, min/max performance data taken with

VA = VCP = 1.8 V; VL = VD = 1.8 V; VP = 3.6 V; TA = +25°C; measurement bandwidth is 20 Hz–90 kHz; ASP_SPRATE = 0110 (LRCK = 192-kHz mode);

PDN_XTAL = 0, MCLK_INT = 1, and MCLK_SRC_SEL = 00 (crystal frequency fXTAL = 22.5792 MHz); Volume = 0 dB; when testing noise related

specifications (dynamic range, THD+N, idle channel noise), no external impedance on REFx.

1.This table also applies to external VCP_FILT supply mode: CS43198 power up procedure is per description in Section 5.12.1; EXT_VCPFILT = 1;

VCP_FILT+ and VCP_FILT– comply to

Table 3-2 when EXT_VCPFILT = 1; in this mode, HV_EN must be set to 1.

Wideband Flatness Mode Parameter 2,3

2.One LSB of triangular PDF dither is added to PCM data.

3.Referred to the typical full-scale voltage. Applies to all THD+N and dynamic range values in the table.

Table 3-7. Combined DAC Digital, On-Chip Analog and AOUTx Filter Characteristics

Test conditions (unless specified otherwise): The filter characteristics have been normalized to the sample rate (Fs) and can be referenced to the desired

sample rate by multiplying the given characteristic by Fs. Single-Speed Mode refers to 32-, 44.1-, and 48-kHz sample rates. Double-Speed Mode refers

to 88.2- and 96-kHz sample rates. Quad-Speed Mode refers to 176.4- and 192-kHz sample rates. Octuple-Speed Mode refers to 352.8- and 384-kHz

sample rates. MCLK_INT is an integer multiple of Fs; HPF disabled; no DC offset applied; group delay does not include serial port delay.
