AK4132
96kHz 24bit Sample Rate Converter
1. General Description
The AK4132 is an 2ch digital sample rate converter (SRC). It converts sample rate of the input audio
source (from 8kHz to 96kHz) to 44.1kHz or 48kHz. It is possible also to convert 8kHz, 16kHz or 24kHz
into 8kHz, 16kHz or 24kHz. The AK4132 has an internal oscillator and does not need any external
master clocks. It contributes simplifying a system configuration. The AK4132 is suitable for the
application interfacing to different sample rates such as Car Audio Systems and DVD recorders.

12 VD18
I Internal Digital Power Supply Pin, 1.7 1.9V (VSEL= “H”)
Regulator Output Pin, Typ. 1.8V (VSEL= “L”)
Current must not be taken from this pin. A 10μF (±30%; including
O the temperature characteristics) capacitor should be connected
between this pin and DVSS. When this capacitor is polarized, the
positive polarity pin should be connected to the VD18 pin.
13 DVSS - Digital Ground Pin
14 DVDD - Digital Power Supply Pin, 3.0 3.6V or 1.7 1.9V
15 VSEL
Internal Digital Power Supply Select Pin
I “H”: External Power Supply
“L”: Internal Regulator
16 PDN
Power-Down Mode Pin
“H”: Power Up
I “L”: Power Down and Reset
The AK4132 should be reset once by bringing PDN pin = “L”
upon power-up.
Note 1. All input pins should not be allowed to float.
Note 2. CM, ODIF and IDIF must be changed when the PDN pin = L.
