4.0
The following key applies to all tables:
4.1
All TDM Interface signals are 5 V tolerant.
All TDM Interface inputs (including data, clock and frame pulse) have internal pull-down resistors so they can be
safely left unconnected if not used.
4.1.1
There are three interfaces possible among the ZL5011x.
The ZL50117/20 supports four TDM ports [3:0] at 2 Mbps, or one TDM port [0] at 8 Mbps or one unstructured TDM
port [0] for J2/E3/T3.
The ZL50116/19 supports two TDM ports [1:0] at 2 Mbps, or one TDM port [0] at 8 Mbps (up to 64 DS0).
The ZL50115/18 supports one TDM port [0] at 2 Mbps, or one TDM port [0] at 8 Mbps (up to 32 DS0)

TDM port serial data input streams. For
different standards these pins are given
different identities:
ST-BUS: TDM_STi[3:0]
H.110:
H-MVIP: TDM_HDS[3:0]
Triggered on rising edge or falling edge
depending on standard. At 8.192 Mbps only
stream [0] is used. Stream [0] is used for
unstructured J2 or T3/E3 on the
ZL50117/20.
