DESCRIPTION
Connects DVCC1 to LVCC1. This shunt reduces the number of supplies
required to operate the EV kit.
Disconnects DVCC1 from LVCC1. The 2-pin header can be utilized for
supply current measurements.
The MAX9247/MAX9248 EV kit provides a proven design
to evaluate the MAX9247 27-bit, 2.5MHz to 42MHz
DC-balanced LVDS serializer and the MAX9248 27-bit,
2.5MHz to 42MHz DC-balanced LVDS deserializer. The
MAX9247 serializes 27 bits of parallel input data, 18 bits
of video, and 9 bits of control to a serial data stream.
The MAX9248 deserializes the LVDS serial input, which
converts to 18 bits of parallel video data and 9 bits of
parallel control data.
The MAX9247 accepts 27-bit parallel data, 18 video data
bits, and 9 control data bits. The 27-bit pattern is sup-
plied to the EV kit by connecting a data generator to the
four 20-pin headers (H6–H9), or by connecting selected
pins of H6–H9 to high/low LVCMOS/LVTTL states. See
Table 2 for input bit locations designated on H6–H9.
The MAX9247 DE_IN pin is accessible through header
H6-13. Driving the pin high selects RGB_IN[17:0] to be
latched. Driving the pin low selects CNTL_IN[8:0] to be
latched.
The MAX9247 parallel input clock (PCLK_IN) is acces-
sible through H5-5 or SMA connector P4 (see Table 3).
Apply a clock frequency to the access points, which
latches data and control inputs and provides the PLL
clock.
The MAX9248 reference clock (REFCLK) input is acces-
sible through H3-5 or SMA connector P3 (see Table 3).
Apply a reference clock to the access point that is within
Q2% of the MAX9247 serializer PCLK_IN frequency.
The MAX9248 outputs 27-bit parallel data, 18 video data
bits, and 9 control data bits at LVCMOS/LVTTL levels on
the 40-pin headers (H1 and H2). To sample the 27-bit
