3 Characteristics and Specifications

Table 3-4. Combined DAC Digital, On-Chip Analog, and HPOUTx Filter Characteristics

Test conditions (unless specified otherwise): TA = +25°C; MCLK = 12 MHz, MCLK_SRC_SEL = 0, FsINT = 48 kHz; path is internal routing engine to

HPOUTx, analog and digital gains are all set to 0 dB; HPF disabled.

Parameter 1

1.Response scales with FsINT (based on internal MCLK). Specifications are normalized to FsINT and denormalized by multiplying by FsINT.

Total group delay 2

2.Informational only; group delay cannot be measured for this block by itself. An additional

5.5/Fsint group delay may be present through the serial ports

and internal audio bus.

Table 3-6. SDIN to HPOUTx with SRC-Enabled Datapath Characteristics

Test conditions (unless specified otherwise): LRCK = FsINT = FsEXT = 48 kHz; MCLK = 12 MHz; HPF disabled; passband/stopband levels normalized to

0.417x10–3 FsEXT; entire path characteristics including serial port + SRC + DAC + HPOUT.

Parameters 1

FsEXT is the external sample rate (LRCK/FSYNC frequency). Response scales with FsEXT.
