Detailed Description
The MAX9595 is a switch matrix that routes audio and
video signals between different ports using the I2C
interface. The ports consist of the MPEG decoder out-
put, and two SCART connectors for the TV and VCR.
Per EN50049 and IEC 933, the encoder can only input
a signal to the SCART connector, while TV and VCR
SCART connectors are bidirectional.
The MAX9595 circuitry consists of four major sections:
the video section, the audio section, the slow- and fast-
switching section, and the digital interface.
The video section consists of clamp and bias circuitry,
input buffers, reconstruction filters, a switch matrix, a
Y/C mixer, and output buffers. All video inputs are AC-
coupled through a 0.1F capacitor to set an acceptable
DC level using clamp or bias networks. The bidirection-
al red/chroma outputs can be connected to ground
using I2C control to make them terminations when
red/chroma is an input (see the Video Inputs section).
The audio section features an input buffer, a switching
matrix, volume- or gain-control circuitry, and output dri-
vers. The audio inputs are AC-coupled through a 0.1F
capacitor. The TV output audio path has volume control
from -56dB to +6dB in 2dB steps, while the VCR output
audio path has volume control from -6dB to +6dB in
6dB steps. The MAX9595 can be configured to switch
inputs during a zero-crossing function to reduce clicks.
The slow-switching feature allows for bidirectional, tri-
level, slow-switching input and output signals at pin
VCR_SS and TV_SS, respectively. The slow-switching
signals from the VCR set the aspect ratio or video source
of the TV screen. If INTERRUPT_OUT is enabled, then
INTERRUPT_OUT changes to a high-impedance state if
any of the slow-switching inputs change logic levels. See
the Slow Switching section.
