Pixel Link Transmitter
INAP125T12
INAP125T24
The INAP125T12/24 is a transmitter for the new Auto-
motive PIXel (APIX) link for display and camera based
point-to-point applications. The APIX link features an
uni-directional pixel and full-duplex sideband data trans-
mission over one single pair of shielded twisted pair
(STP) copper cable. The upstream sideband can also be
transmitted over a separate pair of wires to serve the re-
quirements for automotive applications. In addition this
wire may be used for power supply.
Features:
• Up to 1 GBit/s Downstream Link
• Up to 62.5 MBit/s Upstream Link
• Low EMI, Two- or Four-Wire Full Duplex Link
• Accepts wide spread spectrum pixel clock
• +15 m Distance with low profile STP cables
• 10/12/18/24 bit pixel Interface
• Configurable sampling edge for pixel data
• DC-balanced line coding to support AC
coupling
• Line Driver Current and Pre-Emphasis
adjustable
• Extended Temp. Range: -40 to +105°C
• AEC-Q100
The INAP125T12 video interface supports color widths
of 10 and 12bit, the INAP125T24 widths of 10, 12, 18
and 24bit. The interface can be configured individually to
match all popular display and image sensor interfaces.
The pixel interface is able to handle a wide spread pixel
clock for lowest EMI.
The INAP125T12/24 transmitter features dedicated
high-speed outputs with adjustable drive current and
pre-emphasis to facilitate the adaptation to different link
distances and cable qualities while offering maximum
data integrity and full EMI compliance.
