The MAX9526 EV kit is a fully assembled and tested
surface-mount PCB that contains a MAX9526 IC. The
MAX9526 is a low-power, high-performance multistan-
dard video decoder.
External passive video switch U5 (MAX4586) allows
evaluation of recovery from asynchronous external mul-
tiplexer switching. LDO linear regulator U3 (MAX8511)
powers the MAX9526 1.8V digital and analog supplies.
LDO linear regulator U4 (MAX1658) supplies 3.3V to
the rest of the board. Low-voltage TTL buffer U2
(74AVC16244) drives the 3.3V ITU-R BT.656 bit-parallel
interface-compatible signals on header H1. Header H2
provides access to the I
and R25 pull up SCL and SDA. The microcontroller cir-
cuitry (U9, U10, U11, and U12) is equivalent to Maxim’s
MAXQ2000-based MINIQUSB board.

MAX9526 Evaluation Kit
U6 (ADV7176A) reconstructs the digital ITU-R BT.656
bit-parallel interface signals into component analog
video output. U7 (MAX9584) buffers and filters the DC-
coupled outputs U/BLUE, Y/GREEN, and V/RED.
Optional U8 (CLC021AVGZ) converts the parallel digi-
tal ITU-R BT.656 bit-parallel interface signals into differ-
ential serial digital output (SDO).
To use the MAX9526 EV kit with a user-supplied I
interface, first cut the JU11 and JU12 default traces,
disconnecting SCL and SDA from the on-board micro-
controller. If the user-supplied I
SCL/SDA pullup resistors, then disable on-board pullup
resistors R24 and R25 by cutting the JU3 and JU4
default traces. Lastly, connect the SCL, SDA, and GND
signals to the corresponding test points on header H2
on the MAX9526 EV kit board.
