Description: DEM Reclock Board for Philips TDA1541A DAC If you have a TDA1541A CD player or DAC and you want DEM reclock modification, I recommend this DEM reclock board. Originally, a 470pF capacitor is connected between pin 16 and 17 and the internal oscillator is free-running. Instead of the internal oscillator, this DEM reclock board provides BCLK (or divided clock) to pin 16 and inverted clock to pin 17. DEM operation will be synchronized with incoming audio data. As a result, you will get more solid and clear sound. I think this document will help your understanding. "Advanced re-clocking for TDA1541 based CD players" https://studyres.com/doc/7898405/advanced-re-clocking-for-tda1541-based-cd-players Performance depends on the lot number of TDA1541A and individual variations. I do not guarantee all of TDA1541As work well with this board. If you have two or more TDA1541As, test all of them. This board is for TDA1541"A". It does not work with TDA1541(non-A). [How to install] 1. Remove TDA1541A. Cover Pin 16 and 17 with insulating tape. (Fig. A) 2. Mount the DEM reclock board so the notch mark meets the socket notch. (Fig. B) 3. Mount TDA1541A so the socket notch meets the notch mark on the DEM reclock board. (Fig. C) [Reclock setting] Reclock frequency is selectable with a jumper (Fig. D) If it does not lock or it causes noise, select a lower frequency (f/2 or f/4). Before changing a jumper, please power off the system. SAA7220 NOS f (bclk) 5.6MHz 2.8MHz f/2 2.8MHz 1.4MHz f/4 1.4MHz 0.7MHz I recommend NOS operation. (A NOS jumper socket is available separately) TDA1541A is not included. A fully mounted DEM reclock board only. (Please do any replacement at you own risk.
