GENERAL DESCRIPTION
audio or compressed audio including Dolby® Digital, DTS®,
and THX®.
The AD9389A-BBCZ is an 80 MHz, high definition multimedia
interface (HDMI) v.1.2a transmitter. It supports HDTV formats
up to 720p/1080i, and computer graphic resolutions up to XGA
(1024 × 768 @ 75 Hz). With the inclusion of HDCP, the AD9389A
allows the secure transmission of protected content as specified
by the HDCP v1.1 protocol.
The AD9389A helps to reduce system design complexity and
cost by incorporating such features as an internal MPU for
HDCP operations, an I2C master for EDID reading, a single
1.8 V power supply and 5 V tolerance on I2C and hot plug
detect pins.
The AD9389A supports both S/PDIF and 8-channel I2S audio.
Its high fidelity 8-channel I2S can transmit either stereo or 7.1
surround audio at 192 kHz. The S/PDIF can carry stereo LPCM
Fabricated in an advanced CMOS process, the AD9389A is
available in a space saving, 64-lead LFCSP surface-mount
package. The LFCSP package is specified from 0°C to 70°C.

AD9389A
PCB LAYOUT RECOMMENDATIONS
The AD9389A is a high precision, high speed analog device. As
such, to get the maximum performance out of the part, it is
important to have a well laid out board.
Other Input Signals
POWER SUPPLY BYPASSING
The PD/A0 input pin can be connected to GND or supply
(through a resistor or a control signal). The device address and
power-down polarity are set by the state of the PD/A0 pin when
the AD9389A supplies are applied/enabled. For example, if the
PD/A0 pin is low (when the supplies are turned on), then the
device address is 0x72 and the power down is active high. If the
PD/A0 pin is high (when the supplies are turned on), the device
address is 0x7A and the power down is active low.
It is recommended to bypass each power supply pin with a
0.1 μF capacitor. The exception is when two or more supply
pins are adjacent to each other. For these groupings of
powers/grounds, it is necessary to have only one bypass
capacitor. The fundamental idea is to have a bypass capacitor
within about 0.5 cm of each power pin. Also, avoid placing the
capacitor on the opposite side of the PC board from the
AD9389A, as that interposes resistive vias in the path.
The bypass capacitors should be physically located between the
power plane and the power pin. Current should flow from the
power plane to the capacitor to the power pin. Do not make a
power connection between the capacitor and the power pin.
Placing a via underneath the capacitor pads, down to the power
plane, is generally the best approach.
It is particularly important to maintain low noise and good
stability of PVDD (the PLL supply). Abrupt changes in PVDD
can result in similarly abrupt changes in sampling clock phase
and frequency. This can be avoided by careful attention to
regulation, filtering, and bypassing. It is best practice to provide
separate regulated supplies for each of the analog circuitry
groups (AVDD and PVDD).
It is also recommended to use a single ground plane for the
entire board. Experience has repeatedly shown that the noise
performance is the same or better with a single ground
plane. Using multiple ground planes can be detrimental
because each separate ground plane is smaller, and long
ground loops can result.
DIGITAL INPUTS
Video and Audio Data Input Signals
The digital inputs on the AD9389A are designed to work with
signals ranging from 1.8 V to 3.3 V logic level. Therefore, no
extra components need to be added when using 3.3 V logic.
Any noise that gets onto the clock input (labeled CLK) trace
adds jitter to the system. Therefore, minimize the video clock
input (Pin 6: CLK) trace length and do not run any digital or
other high frequency traces near it. Make sure to match the
length of the input data signals to optimize data capture,
especially for high frequency modes (such as 720p or XGA
75 MHz) and double data rate input formats.
The HPD must be connected to the HDMI connector. A 10 kΩ
pull-down resistor to ground is also recommended.
The SCL and SDA pins should be connected to the I2C master.
A pull-up resistor of 2 kΩ to 1.8 V or 3.3 V is recommended.
EXTERNAL SWING RESISTOR
The external swing resistor must be connected directly to the
EXT_SWG pin and ground. The external swing resistor must
have a value of 887 Ω (±1% tolerance). Avoid running any high
speed ac or noisy signals next to, or close to, the EXT_SWG pin.
OUTPUT SIGNALS
TMDS Output Signals
The AD9389A has three TMDS data channels (0, 1, and 2) that
output signals up to 800 MHz as well as the TMDS output data
clock. To minimize the channel-to-channel skew, make the
trace length of these signals the same. Also, these traces need to
have a 50 Ω characteristic impedance and routed as 100 Ω
differential pairs. It is also recommended to route these lines on
the top PCB layer avoiding the use of vias.
Other Output Signals (non TMDS)
DDCSCL and DDCSDA
The DDCSCL and DDCSDA outputs need to have a minimum
amount of capacitance loading to ensure the best signal integrity.
The DDCSCL and DDCSDA capacitance loading must be less
than 50 pF to meet the HDMI compliance specification. The
DDCSCL and DDCSDA must be connected to the HDMI
connector and a pull-up resistor to 5 V is required. The pull-up
resistor must have a value between 1.5 kΩ and 2 kΩ.
INT Pin
The INT pin is an output that should be connected to the microcontroller of the system. A pull-up resistor to 1.8 V or 3.3 V is
required for proper operation: the recommended value is 2 kΩ.
