DS2152, DS2154 Clock Map

Abstract: ApplicaTIon Note 354 provides a logical diagram of the clock map of the Dallas Semiconductor/Maxim DS2154 and DS2152 single chip transceivers (SCTs).

Figure 1 logically describes the clock map of the DS2152 and DS2154 Single Chip Transceivers. Although there is only one Jitter Attenuator, which can be placed in the receive or transmit path, two are shown for simplificaTIon and clarity.

NotesThe PAYLOAD loopback switch is not included on the DS2154

. LTCA = Long Term Clock Average   RLB = Remote LoopBack JAS = Jitter Attenuator Select   FLB = Framer LoopBack DJA = Disable Jitter Attenuator   PLB = Payload LoopBack RCL = Receive Carrier Loss   LLB = Local Loopback LOTCMC = Loss Of Transmit Clock Mux Control RXCLK = Recovered clock from LIU TXCLK = Transmit rate clock for LIU
