Thread Starter 

I am not associated with nor employed by MDHT Labs.

 

Introducing MHDT Labs USBridge USB to S/PDIF Converter:

 

 

USBridge is a true high speed USB Audio Class 2.0 to standard S/PDIF digital signal converter
USBridge is powered by USB line itself, so no further power input is needed
USBridge was designed for audiophile or DAW usages
USBridge is a asynchronous USB2.0 audio device
USBridge uses C-Media's CM6631 as main chip, C-Media's CM66xx were the world’s first commercialized USB2.0 true high-speed audio processors.   

 

C-Media is a leading USB audio specialist in the world with excellent reputation for years.

 

Size: 90x3.2x95mm (w x h x d, case) 90x3.2x115mm (w x h x d, total)

Weight: 200g (7oz)

Sampling frequencies (kHz): 44.1, 48, 96, 192

Resolution (bits): 16, 24, 32(*) bits

Inputs: USB 2.0,

Outputs: S/PDIF x1 (RCA) (BNC upon request), Optical Toslink™ x1, I2S (RJ-45)  

S/PDIF transmitter: 3.3V LVCMOS with 24mA current capability (EIAJ CP1201, IEC-60958 interface standards)

I2S output voltage: 3.3V CMOS with 35mA current capability on each line

Power consumption: Standby:141mA, Operating:148mA

 

Since USBridge is in asynchronous operation, additional oscillators are used for USBridge as the more accurate clock sources and to achieve lower digital signal jitter. 49.152MHz is for 48/96/192KHz sample rate data and 45.1584MHz is for 44.1/88.2/176.4KHz data.  These oscillators are specially ordered by Mhdt Labs for 10 ppm status.

 

Price: $174 excl. shipping.

It seems everyone is bringing these out. Nice price too.

Amazing what marketing will lead you to do.

 

On one hand, asynchronous USB is a good concept and it's good to see products going that way.

 

On the other hand, they're shooting themselves in the foot by cramming in irrelevant parts to attract audiofools: "audiophile" capacitors in a place (digital) where they will rather degrade than improve things and "10ppm oscillators" rather than low jitter clocks.

I like how it can't support 32bit just yet ;).

Looks nice. I love the purple pcb and colorful caps.
