The MAX9595 dual SCART switch matrix routes audio
and video signals between an MPEG encoder and two
external SCART connectors under I
meets the requirements of EN50049-1, IEC 933-1,
Canal+, and BSkyB standards.
The video and audio channels feature input source
selection multiplexers, input buffers, and output buffers
for routing all inputs to selected outputs.
The MAX9595 provides programmable gain control from
+5dB to +7dB in 1dB steps for red, green, and blue com-
ponent video signals. All other video outputs have a fixed
+6dB gain. Additional features include an internal luma
and chroma (Y/C) mixer that generates a composite
video signal (CVBS) to supply an RF modulator output,
and internal video reconstruction lowpass filters with
passband ripple between -1dB and +1dB from 100kHz to
5.5MHz. The MAX9595 TV audio channel features click-
less switching and programmable volume control from -
56dB to +6dB in 2dB steps. The VCR audio output also
has programmable gain for -6dB, 0dB, or +6dB. The
device also generates monaural audio from left and right
stereo inputs. All audio drivers deliver a 3.0V
mum output.
The MAX9595 operates with standard 5V and 12V power
supplies and supports slow-switching and fast-switching
signals. The I
control, and selects the input source for routing.
The MAX9595 is available in a compact 48-pin thin
QFN package and is specified over the 0°C to +70°C
commercial temperature range.
