DS2152，DS2154时钟地图-DS2152, DS21

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.


Figure 1. Clock map.

Notes

The 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
