µPD63210,63210L
16-BIT D/A CONVERTER WITH BUILT-IN DIGITAL FILTER FOR AUDIO
DESCRIPTION
The µPD63210 is a 16-bit dual D/A converter IC for digital audio demodulation, which incorporates an 8-times
oversampling digital filter and operational amplifiers for analog post filters. With few external parts and an easy
substrate design (as to 1-bit D/A), it is suitable for multimedia terminals, MPEG audio equipment, video CDs, game
machines, and electronic musical instruments, etc. To cope with sets for portable applications, a low-voltage operating
version µPD63210L (lowest operating supply voltage = +3.0 V) is also available.
FEATURES
• 16-bit resistor string D/A converter (2-channel) adopted
S/N = 104 dBTYP.; DR = 96 dBTYP. (when VDD = 5.0 V)
• High-performance 8-times oversampling digital filter incorporated
Pass band ripple
: ±0.003 dB
Stop band rejection : 90 dB
• System clock 384/512fs selectable
• Serial input data format selectable
Format for 2’S compliment, MSB first, and backward justification data accommodated;
Input can be selected between 16- and 18 bits
• Full line of low-voltage operating products (µPD63210L)
µPD63210 : VDD = 4.5 to 5.5 V
µPD63210L : VDD = 3.0 to 5.5 V
• Wide operating temperature range (TA = –40 to +85 °C)
• Operational amplifier (2-channel) for D/A converter output incorporated
• Operational amplifier (2-channel) for post filter (LPF) configuration incorporated
• Digital de-emphasis function (fs = 32/44.1/48 kHz) incorporated
• Soft mute function incorporated
• CD double-speed playback function (when µPD63210: 384fs)
• 28-pin plastic SOP (375 mil) adopted

3.4 Digital De-emphasis Function
The IIR digital filter performs de-emphasis operations. The filter can cope with three types of sampling
frequencies (32/44.1/48 KHz) by using the DEFS1 (No.10) and DEFS2 (No.11) pins.

3.5 Soft Mute Function
The soft mute function can be realized by control of the SMUTE (No.13) pin.
When applying the mute, set the value to SMUTE = H. By this, the output level of the D/A converter is
attenuated from 0dB to negative infinity (-∞) in 128 steps. The time required for a complete mute is 1024/fs.
When cancelling the mute, set the value to SMUTE = L. By this, the output level of the D/A converter is
increased from negative infinity (-∞) to 0dB in 128 steps. Figure 3-8 shows the relationship between the control
of the SMUTE pin and the output level of the D/A converter.
When initializing by resetting the system, the mute is cancelled and the output level of the D/A converter
reaches the maximum (0dB).
Don’t input the narrower “H” pulse than 8/fs to pin 13, or analog output signal may become unstable. In this
case, the unstable condition may be kept until system reset or power off.
