MAX9223/MAX9224
Applications Information
PCLKIN Latch Edge
The parallel data input of the MAX9223 serializer is
latched on the rising edge of PCLKIN. Figure 3 shows
the serializer input timing.
PCLKOUT Strobe
The serial-data output of the MAX9224 deserializer is
valid on the rising edge of PCLKOUT. Figure 4 shows
the deserializer output timing.
Power-Down and Power-Up
Driving PWRDN low puts the MAX9223 in power-down
mode and sends a pulse to power down the MAX9224. In
power-down mode, the DLL is stopped, SDO+/SDO- are
high impedance to ground and differential, and the LCDS
link is weakly biased around VDD - 0.8V. With PWRDN
and all inputs low, the combined MAX9223/MAX9224
supply current is reduced to 3.5A or less.
Driving PWRDN high starts DLL lock to PCLKIN and ini-
tiates a MAX9224 power-up sequence. The MAX9223
LCDS output is not driven until the DLL locks. 4096
clock cycles are required for the power-up and link
synchronization, before valid DIN can be latched. See
Figure 6 for an overall power-up and power-down tim-
ing diagram. For normal operation, PCLKIN must be
running and settled before driving PWRDN high.
If VDD = 0, the LCDS outputs are high impedance to
ground and differential.
Ground-Shift Tolerance
The MAX9223/MAX9224 are designed to function nor-
mally in the event of a slight shift in ground potential.
However, the MAX9224 deserializer ground must be
within ±0.2V relative to the MAX9223 serializer ground
to maintain proper operation.
MAX9224 Output Buffer Supply (VDDO)
The MAX9224 parallel outputs are powered from VDDO,
which accepts a +1.71V to +3.465V supply, allowing
direct interface to inputs with 1.8V to 3.3V logic levels.
