Notes
1.
2.
Input leakage currents include high-impedance output leakage for all bidirectional buffers with 3-state outputs.
Pins without pull-up resistors must have a 3 mA output current. Pins requiring pull-up resistors must have 6 mA;
these are pins FRAME#, TRDY#, IRDY#, DEVSEL#, SERR#, PERR#, INT_A and STOP#.
This parameter is to be interpreted as the cumulative edge rate across the specified range, rather than the
instantaneous rate at any point within the transition range.
REQ# and GNT# are point-to-point signals and have different output valid delay and input set-up times than bused
signals. GNT# has a set-up time of 10 ns. REQ# has a set-up time of 12 ns.
For purposes of active or float timing measurements, the high-impedance or ‘off’ state is defined to be when the total
current delivered through the device is less than or equal to the leakage current specification.
RST is asserted and de-asserted asynchronously with respect to CLK.
All output drivers floated asynchronously when RST is active.
V
DD(I2C)
is the extended pull-up voltage of the I
2
C-bus (3.3 or 5 V bus).
Nominal analog video input signal is to be terminated by 75
that results in 1 V (p-p) amplitude. This termination
resistor should be split into 18
and 56
, and the dividing tap should feed the video input pin, via a coupling
capacitor of 47 nF, to achieve a control range from
3 dB (attenuation) to +6 dB (amplification) for the internal
automatic gain control. See also the application notes of the SAA7130HL/34HL.
10. See user manuals SAA7130HL/34HL for Anti-Alias Filter (AAF).
11. Definition of levels and level setting:
a) The full-scale level for analog audio signals V
FS
= 0.8 V (RMS). The nominal level at the digital crossbar switch
is defined at
15 dB (FS).
b) Nominal audio input levels: external, mono, V
i
= 280 mV (RMS);
9 dB (FS).
12. The analog audio inputs (pins LEFT1, RIGHT1, LEFT2 and RIGHT2) are supported by two input levels: 1 V (RMS)
and 2 V (RMS), selectable independently per stereo input pair, LEFT1, RIGHT1 and LEFT2, RIGHT2.
13. V
DDA
= 3.3 V; settings in accordance with B/G standard; FM deviation is
±
50 kHz; f
mod
= 1 kHz; FM sound
parameters in accordance with system A2; NICAM in accordance with EBU specification; 1 k
measurement source
resistance for AF inputs; V
i(SIF)
= 300 mV (p-p); programming registers AGCOFF = 0 and AGCSLOW = 1; level and
gain settings according to note 11; for external components see the application diagram in SAA7130HL and
SAA7134HL application notes; unless otherwise specified.
14. The NICAM values are in accordance with the EBU specification. Audio performance is limited by the dynamic range
of the NICAM 728 system. Due to companding, the quantization noise is never lower than
62 dB with respect to the
input level.
