Notes
1.
2.
Outputs OPL and OPR are measured with external components as recommended in Fig.11.
Total analog performance is limited by dynamic range of the NICAM 728 system. Due to compansion the quantization
noise is never lower than approximately -62 dB with respect to the input level.
Measured with a -30 dB, 1 kHz NICAM 728 input signal.
Note that a transmitter must internally provide at least a hold time to bridge the undefined region (max. 300 ns) of the
falling edge of SCL.
If a fast I
2
C-bus device is used in an up to 100 kbit/s I
2
C-bus system, then the requirement t
SU;DAT
≥
250 ns is always
fulfilled if this device cannot stretch the LOW level of the SCL signal. If a device stretches the LOW level of the SCL
signal, then data to SD9A must be asserted (t
RD(max)
+ t
SU;DAT
) = 1000 + 250 = 1250 ns before the SCL signal is
released to be compatible with the up to 100 kbit/s I
2
C-bus specification.
The output fall time is measured between 3.0 V and 1.5 V for a bus capacitance of 400 pF and an active pull-up.
