The AMBE-1000™ Vocoder Chip has a hardware setting using C_SEL[2-0] that allows
an easy connection to the Lucent CSP1027 as shown in Table 5-A. In this configuration
the AMBE-1000™ will automatically send out appropriate configuration words to the
CSP1027 as shown in Table 5-A. There is no need to put the AMBE-1000™ into sleep
mode for this configuration to take place.
Figure 8-A Digital Interfacing to the Lucent CSP1027
*see Table 5-A
The CD_SADD pin is only used for this interface to distinguish the programming data
from regular sampled data. See Figure 8-B below.
Figure 8-B CD_SADD Timing for CSP1027
Remember that if configuration words other than those shown in Table 5-A are desired,
then the AMBE-1000™ must be put into sleep mode and a Command Frame with
ID=0x03 must be sent as described in section 4.1.14.4.
