• Manufacturer Part Number: ml7084-001
• Description: 4ch Voip Codec
• Manufacturer: Oki Semiconductor

• PCM Signal Output Pin for CH0b/CH1b (PCMO_b)
Note:
Note that if a PCM interface is selected for both a front end interface and a speech codec interface, the PCM output
signal of each interface will be output by multiplexing to the upper 8 bits and lower 8 bits of one time slot.
For each of the buffers, time slot and enable/disable settings can be Mbde individually using the following setting
method.
<Setting Method>
1) Select TS#1 to TS#16 with the PCMb output buffer n setting register (PCM_OTSn[3:0]_b: n=0 to 3).
2) The output of the PCM data at the applicable time slot position will be started by setting the PCMb output buffer
Note: Using a PCM interface as a speech codec interface is not currntly supported; therefore, OTS0a, OTS1a,

The PCM data to be output from PCMO_b can be output to up to two time slots with the two buffers (16-bit width)
PCMOb ouptut buffer 0 (OTS0b) and PCMOb output buffer 1 (OTS1b). These two buffers are assigned to output
the PCM signals described below. (See also the Block Diagram of this LSI.)
n enable control register (PCMOn_EN_b; n = 0 to 3) to “1”.
Note that PCM data is output using the upper 8 bits or lower 8 bits selected by the PCMb output buffer n
upper/lower selection register (OTSn_SEL_b), and the unselected 8 bits will be FFh (Hi-Z) output.
Furthermore, specify either upper 8 bits or lower 8 bits of 16-bit width with the PCMb output buffer n
upper/lower selection register (OTSn_SEL_b).

− PCMOb output buffer 1 (OTS1b) :
If a PCM interface is selected as a front end interface, the PCM signal for CH0b is output. Additionally, if a
PCM interface is selected as a speech codec interface, the PCM signal for CH0b is output.
If a PCM interface is selected as a front end interface, the PCM signal for CH1b is output. Additionally, if a
PCM interface is selected as a speech codec interface, the PCM signal for CH1b is output.
OTS0b and OTS1b will be used for PCM signal output via a front end interface. If it is necessary to use a
PCM interface as a speech codec interface, contact our sales personnel.
