Devices Characteristics:
Two-channel Digital Interpolation Filter and data in-phase processor for digital audio.
208-pin PQFP package, Manufactured on 300-mm wafers using, 90-nm low-k dielectric process. Devices offer advanced features for high-performance digital signal processing (DSP) applications with up to 250-MHz.
Data and Master-clock in-phase processing just without jitters.

Filter Configuration:
Core power supply voltage: 1.2V.
I/O power supply voltage: 3.3V.
Programmable Functions: hardware control mode.
Two-channel 1-times / 2-times / 4-times / 8-times oversampling , supports Bypass mode (NOS mode.).
Three-stage linear-phase ( group delay distortion : Zero)  FIR filter configuration.

Filter Characteristics:
Stopband Attenuation:
V50dB / -90DB / -130DB.
Passband: 00.4535Fs.
Passband Ripple: within 0.00001dB.

 Input/Output:
Input Data Formats: I2S
Input Word Length: 16, 20, or 24 Bits
Output Word Length: 16, 20, or 24 Bits
Output Data Formats: MSB-First, Binary Two
s Complement
Sampling Frequency: 32kHz to 96kHz( In DAC Reference One/Two , because they Applied DIR9001 receiver chip, so only
Supports 24 Bits, 32-96K)
Supports 24 Bits, 96 kHz Sample Rate
 
Master-Clock:
Clock Autodivide Circuit Supports four Master-Clock Frequencies : 256FsB384FsB512FsB768Fs
Built-in two groups high performance PLL , supports low jitter Master-Clock output.

Note:     ON mean the jumper push on. (On the old DSP-1 is DIP switch, ON mean put the DIP switch to ON side)
              OFF mean the jumper pull off.(On  the old DSP-1 is DIP switch, ON mean put the DIP switch to OFF side)
