1.3.2 Low-speed Upstream Sideband Data Channel (SB0)
The low-speed upstream sideband data channel consists of one 4 Mbps data channel with a 4-bit parallel interface (or 4
individual 1 Mbps data channels, each consisting of a 1-bit serial interface) and one synchronous clock output (SB0_CLK).
1.3.3 High-speed Upstream Sideband Data Channel (SB1)
The high-speed upstream sideband data channel has a 2-bit wide data interface. Different operating modes can be
selected. The maximum bandwidth is 111 Mbps. This can be used for any generic data link e.g. a low-resolution graphics
channel or a CMOS image sensor.
In asynchronous clocking mode an external clock can be applied into SB1_CLKI of the INDR. The range of the external
acceptable clock frequency is 0 – 55 MHz. In synchronous mode data are read into the INDR using the synchronous clock
frequency of 55 MHz being output at SB1_CLKO. In both cases the transferred data are available at the INDT with a fixed
clock of 55 MHz.
1.3.4 Low-speed Downstream Sideband Data Channel (SB2)
The low-speed downstream sideband data channel consists of one 4 Mbps data channel with a 4-bit parallel interface (or 4
individual 1 Mbps data channels, each consisting of a 1-bit serial interface) and one synchronous clock output (SB2_CLK).
1.3.5 High-speed Downstream Sideband Data Channel (SB3, SB42).
The INDT/R166B (INDT/R331B) features one (two) high-speed downstream sideband data channels, each with a 2-bit
wide data interface. Different operating modes can be selected. The maximum bandwidth is 132 Mbps (2 x 132 Mbps).
In asynchronous clocking mode an external clock can be feed into SB3_CLKI (and SB4_CLKI2) of the INDT. The range of
the external acceptable clock frequency is 0 – 66 MHz. In synchronous mode data are read into the INDT using the
synchronous clock frequency of 66 MHz being output at SB3_CLKO (and SB4_CLKO2). In both cases the transferred data
are available at the INDR with a fixed clock of 66 MHz. In sampling mode, the sideband data are sampled with an internal
sampling clock at 66 MHz.
