`Specification of Physical Layer
`
`1 Introduction
`
`The Physical Layer of a MOST network supports the optical transmission of the bit stream between
`MOST Devices. This document describes and defines the “MOST Specification of Physical Layer”.
`
`The physical connection of two MOST devices is called “point-to-point-link”. The “MOST Specification
`of Physical Layer” is organized in four specification points along an individual “point-to-point-link”. The
`location of the specification points is shown in Figure 1-1.

`
`Specification point No.1 and specification point No. 4 are pure electrical interfaces. They define the
`electrical signal requirements between a MOST transceiver unit (with its input Rx and output Tx) and
`an optical ⇔ electrical converter (e.g. electrical signal timings, electrical signal levels, electrical signal
`distortion).
`
`Specification point No. 2 and specification point No. 3 define the optical and mechanical properties of
`the interfaces between a MOST device and a wiring harness (e.g. wavelength, optical signal timing,
`optical power budget, optical signal distortion, connector interface drawings). All parameters and
`definitions required for individual specification points are summarized in tables that are referenced in
`Table 1-1.
`
`Individual MOST devices that fulfill the “MOST Specification of Physical Layer” are basically
`compatible to each other. Due to several point-to-point-links within a MOST network ring, system
`network functionality is only ensured, when “MOST Specification of Physical Layer” is fulfilled by every
`individual point-to-point-link and the special requirements of section 2.6 are considered. The number
`of MOST devices is equal to the number of point-to-point-links.
`
`There are special tests defined to check the physical layer compliance of MOST devices. These tests
`are part of the general MOST compliance test (see references in Table 1-1).

`
`2 Electrical and Optical Parameters
`
`2.1 General Remarks
`
`A MOST frame consists of 512 bit. The bit rate B of the MOST system can be calculated as
`B = 512bit * FS for a given sampling rate (FS = Frame Sync). Due to biphase mark coding the
`smallest pulse length is given as UI = 1/(2B) with the Unit Interval UI.
`
`Within a MOST pattern, only three different pulse lengths can occur. They are called UI, 2UI, 3UI. In
`case of FS = 44.1kHz, the Bit Rate B and the Unit Interval UI are given as B = 22.5792 MBit/s and
`UI = 22.14ns.
`
`The points Tx and Rx represent the interfaces of the used MOST network transceiver. They are not
`specified here. However, they have to fulfill the requirements of SP1 and SP4. This includes possible
`worsening due to the transmission between MOST network transceivers and the respective EOC and
`OEC.
`
`Please note:
`All timing parameters in the following tables are specified for high pulses!
`
`The pulse width variation (tpwv) is defined as the sum of the Average Pulse Width Distortion plus high-
`frequency jitter (see Figure 2-1). The limits for the pulse width variation are valid for all data elements
`(Length of high pulse = n*UI; n=1,2,3). Absolute pulse width has to be within the limits
`
`n*UI – (UI-tpwv(min))
`and
`n*UI + (tpwv(max)–UI)
`
`with an error rate of better than 10-9.
`
`The Average Pulse Width Distortion, defined as tapwd = (tpwmx + tpwmn – 2UI)/2, is illustrated in Figure
`2-1. The values tpwmx and tpwmn are maximum and minimum measured values, so that pulses with a
`width of less than tpwv(min) or more than tpwv(max) occur with a probability of less than 10-9. The example
`of Figure 2-1 shows the limit of tpwmx = tpwv(max) and tpwmn = tpwv(min).

`
`2.6 Additional Requirements for System Design
`
`The parameters given for the specification points SP1 ... SP4 are the base for a accurate point-to-
`point link. Looking on a MOST-network with multiple nodes there are additional system-aspects.
`
`The distortion on a MOST-data-stream, described by the parameters Pulse Width Variation and
`Average Pulse Width Distortion, has to be divided into static and dynamic distortion. All static
`distortion and parts of the dynamic distortion will be eliminated by an active Most network transceiver
`chip. The remaining part of the dynamic distortion will be reduced by the transceiver chip and will
`appear on transmitter-side (SP1). The amount of dynamic distortion on SP1 depends on:
`
`• Dynamic distortion at the input of the transceiver chip (SP4)
`
`• Transfer-function of the transceiver-PLL
`
`The signal quality on SP4 is mainly influenced by the OEC-technology (worst case parameters are
`given in Table 2-3 and
`Table 2-4) and by the optical input power at SP3. The data recovery unit inside the transceiver chip is
`based on the sampling clock generated by the PLL (Phase Locked Loop) and will attenuate the
`incoming dynamic distortion.
`
`In a MOST network, the total dynamic distortion based on the Master-TX-signal will accumulate from
`node to node. Depending on the signal quality at the input of a slave device the total amount of
`distortion at the output of such a node will increase or decrease.
`
`Therefore, system stability requires a well defined number of links running at high transmission quality
`to compensate low quality links.

`3.2 Connector Interface Loss
`Figure 3-1 shows details of the connector insertion loss Dcon between devices and cabling:
`
`• The attenuation of optical power may not exceed D2conmax = 2.5 dB,
`when optical signal transits from SP2 into the cabling fiber.
`• The attenuation of optical power may not exceed D3conmax = 2.5 dB,
`when optical signal transits from the cabling fiber into SP3.
`
`Please note:
`The maximum connector attenuation is a part of the “MOST Specification of Physical Layer”.
