Application examples as an Analog-S/P DIF converter

• Connection example when substituting the input of personal computers (audio card)

An example using an AC2496 as an analog-S/P DIF converter connected to the audio card installed in a personal computer for converting the analog audio signal to S/P DIF digital signal and recorded.

<Notes on cable connection>

When plugging or unplugging the interconnect- ing cables be sure to do so only after switching off the power to the AC2496.

Otherwise, noise could result.

• Setup of the AC2496

When the AC2496 is to be used as an Analog-S/P DIF converter, it must be setup as explained below.

<Notes on setup>

When changing the select switches of AC2496, be sure to do so only after switching off power to AC2496.

Should the switches be manipulated with power on, it could create noise.

If WORD clock cannot be in- put, switch CLOCK SW to "INT." The terminate switch can be set to either position.

This switch will have no affect at output of S/P DIF digital sig- nals.

The AC2496 reference level should be set to match the analog signal output level that is connected.

This is set to match the sampling fre- quency of connected equipment.

For S/P DIF digital signals, it will comply also to "96kHz."

Using the AC2496 as a digital master

In the explanations up to this point, the AC2496 was used as the slave. In other applications, the AC2496 can be used as the master.

As shown in schematic at right, by applying

WORD clock from the AC2496 WORD OUT port WORD clock to digital equipment installed with WORD IN,

such equipment can be synchronized with the AC2496 WORD clock.

<Note>

When using the AC2496 as the master, set its switch to "INT" and the external digital equipment to "sync mode."
