description
MuxIt is a family of general-purpose, multiple-chip building blocks for implementing parallel data serializers and
deserializers. The system allows for wide parallel data to be transmitted through a reduced number of
transmission lines over distances greater than can be achieved with a single-ended (e.g., LVTTL or LVCMOS)
data interface. The number of bits multiplexed per transmission line is user selectable, allowing for higher
transmission efficiencies than with other existing fixed ratio solutions. MuxIt utilizes the LVDS (TIA/EIA-644-A)
low voltage differential signaling technology for communications between the data source and data destination.
The MuxIt family initially includes three devices supporting simplex communications: the SN65LVDS150 phase
locked loop frequency multiplier, the SN65LVDS151 serializer-transmitter, and the SN65LVDS152 receiver-
deserializer.
The SN65LVDS152 consists of three LVDS differential transmission line receivers, an LVDS differential
transmission line driver, a 10-bit serial-in/parallel-out shift register, plus associated input and output buffers. It
receives serialized data over an LVDS transmission line link, deserializes (demultiplexes) it, and delivers it on
parallel data outputs, DO–0 through DO–9. Data received over the link is clocked at a factor of M times the
original parallel data frequency. The multiplexing ratio M, or number of bits per data clock cycle, is programmed
with configuration pins (M1 → M5) on the companion SN65LVDS150 MuxIt programmable PLL frequency
multiplier. Up to 10 bits of data may be deserialized and output by each SN65LVDS152. Two or more
SN65LVDS152 units may be connected in series (cascaded) to accommodate wider parallel data paths for
higher serialization values. The range of multiplexing ratio M supported by the SN65LVDS150 MuxIt
programmable PLL frequency multiplier is between 4 and 40. Table 1 shows some of the combinations of LCI
and MCI supported by the SN65LVDS150 MuxIt programmable PLL frequency multiplier.
