2 [TDAA TRODUCTION TDAA DAC is the classic bit DAC developed by Philips, which has been employed for high-end audio equipments for over many years. This DAC uses with digital filter SAA0 and the digital audio receiver IC CS or CS, with x oversampling. The output stages are implemented by two stage opamps and large AC coupling capacitors. There are totally decoupling capacitors around the TDAA chip, also large decoupling are used for each supply lines. The digital and analog grounds are well separated before they meet at the terminal ground. Also, this DAC can be reconfigured into to non-oversampling mode. Page

3 [TDAA FEATURES One TDAA/TDA, one CS/CS, and one SAA0. Input: S/PDIF Output: stereo single-ended signals (Vrms) Seven independent built-in voltage regulation circuits to power different units. Built-in full wave rectification circuits for AC power supply. Signal paths are designed with minimum parasitic. Dedicated ground and power rails layout design. Four large reservoir decoupling capacitors for power rails. Power requirements: two -0V DC, one V AC, and one 9-V AC. PCB dimension: 0mm (W) x 0mm (L) PCB thickness:.mm, double layer, oz copper. Page

4 [TDAA PROCEDURES. Solder all the components according to the schematic, part list and the photo. Notice the direction of the polarities of the electrolytic capacitors. There is no direction for the thin film capacitors. Either uses K ohm for R, 0.0uF for C for CS. Do not assemble C; R = 0ohm and C = nf for CS Or Use 0 Ohm for R and 0.uF for C, 00pF for C.. To ensure power supply is functional, please do the follow test before plugging in any ICs and adjust the resistor trimmer (blue) so that the following requirement are met: Measure L, uh (V supply for SAA0) Measure L, uh (-V supply for TDA) Measure L, uh (-V supply for TDA) Measure L, uh (V supply for TDA) Measure L, uh (V supply for CS) Measure L, uh (V supply for CS) Measure C9, 00nF (+V supply for AD9/NE/OPA) Measure C0, 00nF (-V supply for AD9/NE/OPA). After checked the power supply, plug in the ICs and turn on the power supply.. Enjoy it. For Non-Overclock Sampling (NOS). U pin (BCK) to U pin, U pin (DATA) to U pin, U pin (WS) to U pin.. The CS must be put into "master" mode because the standard way its done on the PCB uses the CS in "slave" mode for the re-clocking. To put into master Page

5 [TDAA mode: remove one leg on the CS adaptor board which is for M0 selector pin to remove the +V to this pin then attach M0 to GND. Then the CS is in master mode and will generate word clock and LR clock from the SPDIF. Master mode is m0=0v m=+v m=0v m=0v Thanks Erin for providing the information CHECKLIST.

7 [TDAA TESTG & DEBUGGG For CS/C and SAA0, check the rms voltages in the following diagram.. For TDAA, P, P: +V; P: -V; P: -V; P: 0V. The signal amplitude (RMS) and the clock frequency: P LE: ~.KHz, P SCK: ~.MHz, P SDATA: V digital signal.. It is normal that the output P AOR and P AOL is very weak ~0mV.The corresponding waveforms are shown as following: Page
