랩탑에 물릴 용도로 쓰려고 하는 DAC입니다.
연결은 SPDIF로 하려고 합니다.

1.



Dac chip : TDA1543
digital receiver : DIR9001 (CS8412/4/6보다 좋은 칩이라고 함)
Precision Clock : 1ppm 12.0000Mhz TCXO
Decoupling capacitors for TDA1543 chips: Eight NEC TOKIN 10uf/25v SMD type capacitors, one for each tda1543 chip
Adjustive capacitors for voltage regulator: Two Rubycon XYF 25uf/25v Long Life/Low impedance 105 degree C tolerance


2.


analog output: unbalanced output (RCA) , 1.6V rms
rigid anodized aluminium chasiss in a compact size (42 mm x 112 mm x 119 mm)
cool and stylish looking 12mm translucent acrylic front panel, CNC machined
Low Jitter receiver from ST + Philips TDA1543 combo for digital signal reception and conversion
passive I/V conversion using high quality Vishay resistor to preserve signal integrity
onboard precision voltage regulator for individual ICs
"shunt" regulator with constant current source for DAC chip
professionally fabricated PCB with customized layout
fully "plug-and-play", enjoy your music right away
high quality DC power supply (100 - 240V ready)


2번째가 기판은 더 프로페셔널해 보이는데 칩은 1번째가 더 많이 들어간거 같고
가격은 1번째가 200불이고 2번째는 300불이 좀 안됩니다.
그러니까 가격은 100불 차이죠.
