MAX9598
Low-Power Audio/Video Switch for
Dual SCART Connectors
______________________________________________________________________________________

Power Consumption
The quiescent power consumption and average power
consumption of the MAX9598 are very low because of
3.3V operation and low-power circuit design. Quiescent
power consumption is defined when the MAX9598 is
operating without loads and without any audio or video
signals. Table 5 shows the quiescent power consump-
tion in all four operating modes.
Average power consumption is defined when the
MAX9598 drives typical signals into typical loads. Table 6
shows the average power consumption in full-power
mode and Table 7 shows the input and output conditions.
S-Video
The MAX9598 supports S-video from the set-top box to
the TV, set-top box to the VCR, and VCR to the set-top
box. S-video was not included in the original SCART
specifications but was added afterwards. As a conse-
quence, the luma (Y) signal of S-video shares the same
SCART pin as the CVBS signal. Likewise, the chroma
(C) signal shares the same SCART pin as the red sig-
nal. The pins that can carry both CVBS and luma have
Y/CVBS in their names, and the pins that can carry red
and chroma have R/C in their names.
Now, the Y/CVBS signals are full duplex while the R/C
signals are half duplex. Therefore, S-video is limited to
being half duplex. The MAX9598 has to transmit a chro-
ma signal and receive a chroma signal on the same
SCART pin, but not at the same time. The 75
Ω resistor
connected to VCR_R/C_OUT must act as a back termi-
nation resistor when the MAX9598 is transmitting chro-
ma signal and as an input termination resistor when it is
receiving a chroma signal. Figure 14 shows how the
MAX9598 transmits a chroma signal to the VCR SCART
connector while Figure 15 shows how the MAX9598
receives a chroma from the VCR SCART connector.
Write a 0 into bit 2 of register 09h to open the pulldown
switch at VCR_R/C_OUT. To close the pulldown switch,
write a 0 into bit 6 of register 0Dh to turn off the output
amplifier, and then write a 1 into bit 2, register 09h. See
Tables 15 and 16.
