Data Sheet
For all input clocks typical values are given although other clock frequencies may
be used, too.
1) The modes TE, LT-T and LT-S can directly be selected by strapping the pins
MODE1 and MODE0. The mode can be reprogrammed in TR_MODE.MODE2-0
where NT and intelligent NT can be selected additionally. In int. NT mode MODE0
selects between NT state machine (0) and LT-S state machine (1).
2) The number of IOM channels depends on the DCL clock, e.g. with DCL=1536
kHz 3 IOM channels and with DCL=4096 kHz 8 channels are available.
3) In LT-T mode the 1536 kHz output clock on SCLK is synchronous to the S
interface and can be used as input for the DCL clock.
4) The direction input/output refers to the direction of the B- and D-channel data
stream across the S-transceiver. Due to the capabilites of the IOM-2 handler the
direction of some other timeslots may be different if this is programmed by the host
(e.g. for data exchange between different devices connected to IOM-2).
