DECODER OUTPUT — SHORT FRAME  
seen while DOE is high. The enable can be used to extend  
the LSB to a full DDC period and/or cause the eight bits of  
data to be recirculated to the output pin until the enable falls.  
Figure 7 shows the timing of the decoder output in short  
frame mode.  
The DDO will provide the 8–bit PCM word for the decoding  
rate that was selected for this frame of data on the decoder  
input pins. The data is loaded into the MC145532 during one  
frame, decoded on the next frame, and read during the third  
frame.  
STANDARDS INFORMATION  
The following standards apply to the MC145532:  
T1.301–1987 — 32 kbps ADPCM  
T1.303–1988 — 24 kbps ADPCM  
CCITT G.721–1988, G.723–1988, and G.726 — 32 kbps  
and 24 kbps  
DECODER OUTPUT — LONG FRAME  
Figure 8 shows the timing of the decoder output in long  
frame mode. Note that at least eight bits are presented to the  
output, provided that at least two falling edges of DDC are  
CCITT, ITU–T, TIA, and EIA documents may be obtained  
by contacting Global Engineering Documents in the USA at  
(800) 854–7179, or internationally at (303) 397–7956.
