MT88E43B
Preliminary Information

Figure 17 - Input and Output Timing for BT Caller Display Service (CDS), e.g., CLIP
Notes:
1) The total recognition time is t
REC
= t
GP
+ t
DP
, where t
GP
is the tone present guard time and t
DP
is the tone present detect time (refer
to section “Dual Tone Detection Guard Time” on page 57 for details). V
TGt
is the comparator threshold (refer to Figure 4).
2) The total tone absent time is t
ABS
= t
GA
+ t
DA
, where t
GA
is the tone absent guard time and t
DA
is the tone absent detect time (refer
to section “Dual Tone Detection Guard Time” on page 57 for details). V
TGt
is the comparator threshold (refer to Figure 4).
3) By choosing t
GA
=15ms, t
ABS
will be 15-25ms so that the current wetting pulse and AC load can be applied right after the StD falling
edge.
4) SIN227 specifies that the AC and DC loads should be removed between 50-150ms after the end of the FSK signal, indicated by CD
returning to high. The MT88E43B may also be powered down at this time.
5) FSKen should be set low when FSK is not expected to prevent the FSK demodulator from reacting to other in-band signals such as
speech, Tone Alert Signal and DTMF tones.
6) TRIGout is the ring envelope during ringing.
