DS2152, DS2154 Clock Map

Abstract: Application note 354 provides a logical diagram of the clock map of the 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.
