Specifications of PEB20571FV31XT

• Lead Free Status / Rohs Status: Compliant

• Three VIPs connected at data rate of 9.216 Mbit/s: 24 IOM-2000 channels at a clock
4.2.3
During startup the VIP requires 3 frames with the right FSC and DCL_2000 to
synchronize to the DELIC. During this time the VIP is not able to detect commands or
data from the DELIC. Therefore, the delayed reset signal RESIND of the DELIC should
be used to reset the VIP.
4.2.4
All Command/Status bits used for VIP channel programming are divided into one group
used only during initialization, and one group used during normal operation.
4.2.4.1
The bits of this group are used for VIP initialization or in operation modes where an
immediate reaction is not required. The initialization group includes command bits and
the channel address, stored in register TICCMR.
Note: The usage of this group of bits is limited in a way that only one channel may be
In test mode, the command word to VIP_n (CMD_n) and to Channel_m of VIP_n
(CMD_n_m) may be read by the DELIC in the next frame after issuing bits ’RD_n’ or
’RD’. The VIP mirrors the command word exactly as it was received, despite the bits
’WR’, ’WR_ST’, ’RD’. The VIP status is saved in the TRANSIU initialization status
(TICSTR) register, which includes status bits and the channel address.
Note: The commands must not be read during normal operation, since in this case the
4.2.4.2
The bits of this group are used during normal operation, hence they are evaluated in
every frame. They include all VIP receiver status bits and some of the command bits.
The operational mode command/status bits are buffered in the Data RAM.
The VIP receiver status bits do not reflect a status change, but the status itself, i.e. the
current value of the line interface INFOs, until the values change.
The FECV is only reported to the DELIC upon changes.
4.2.4.3
The command/status bits are transmitted/received by the TRANSIU at the same rate as
data transmission rate, starting with the 8 kHz FSC.
