1. CHARACTERISTICS AND SPECIFICATIONS
ANALOG CHARACTERISTICS
Scale Input Sine wave, 984.375 Hz; Fs = 48 kHz BRM, 96 kHz HRM; Measurement Bandwidth is 20 Hz to 20 kHz;
Local components as shown in Figure 5; SPI control mode, Left Justified serial format, MCLK = 256 x Fs for BRM,
128 x Fs for HRM, SCLK = 64 x Fs)
Notes: 1. Referenced to typical full-scale differential input voltage (2 Vrms), Tested with -1 dBFS input.

2. Filter response is not tested but is guaranteed by design.
3. Filter characteristics scale with output sample rate.
4. The analog modulator samples the input at 128 times Fs. For example, input the sample rate is
5. High Pass Filter characteristics are specified for Fs=44.1 KHz.
6.144 MHz for an output sample rate of 48 kHz. There is no rejection of input signals which are multiples
of the sampling frequency (n × 6.144 MHz ±20.0 kHz where n = 0,1,2,3...).
