Data Sheet
3.4
The IOM-2000 interface connects up to three VIPs to DELIC.
DELIC as the communication controller performs parts of the layer-1 protocol, which
enables flexible and efficient operation of the VIP.

Description
IOM-2000 uses an 8-kHz FSC.
Data is transmitted via DX line from DELIC to VIP with
DCL_2000 rising edge. Data is received via DR line from
VIP to DELIC, sampled with DCL_2000 falling edge.
Configuration and control information of VIP’s layer-1
transceivers is exchanged via CMD and STAT lines.
Data and commands for one VIP are transmitted at
3.072 MHz. When DELIC drives 2 or 3 VIPs, the
transmission rate is increased.
In LT-T mode, the VIP provides a reference clock
synchronized to the exchange. In LT-S or U
DELIC is always the clock master to VIP.
