5.4.3 AD1819 Connections

When the AD1819A is enabled on the EZ-KIT Lite board, accessing the audio input and

output jacks on the board is possible. Each of the audio connectors are stereo mini jacks

and accept standard commercially available stereo mini plugs.

The Microphone/Line_in Input jack connects to the LINE_IN_L (left) and LINE_IN_R

(right) pins or the MIC1 and MIC2 of the AD1819A SoundPort Stereo Codec, depending

on the setting of jumpers JP1 and JP2. Jumper settings are explained in Table 5-6.

The LINE Output jack connects to the left (L) LINE_OUT and right (R) LINE_OUT pins

of the codec.

The two expansion port connectors provide access to the bus signals of the ADSP-

21065L. One possibility for the use of these connectors, beyond debugging, is host

control. All interrupts, bus signals, and PWM event signals are available through this

port. For more information, see "Expansion Connectors" section in Chapter 6.

WARNING: External port loading can effect external bus speed and performance.

WARNING: Using the EMAFE interface connector to connect to a MAFE board can

damage the ADSP-21065L EZ-KIT Lite, the MAFE, or both.

Enhanced Modular Analog Front End (EMAFE) connector provides a standard interface

for connecting analog input/output daughter boards. The connector has 96 female pins

arranged in three rows of 32 pins on a right angle connector. The interface supports a

16-bit parallel data path, two serial ports, an interrupt output, and a flag input. Refer to

"EMAFE Expansion" section in Chapter 6 for more information on the EMAFE

interface.

The JTAG header (Figure 5-3) is the connecting point for the JTAG in-circuit emulator

probe. Note that one pin is missing (pin 3) to provide keying. The pin 3 socket in the

mating connector should have a plug inserted at that location.

The EZ-KIT Lite board is shipped with two jumpers installed across pins 7 & 8 and 9 &

10. These jumpers must be removed before installing the JTAG probe. When the JTAG

probe is removed, care must be taken to replace these jumpers to ensure that the ADSP-

21065L processor initializes correctly on power-up.
