• Manufacturer Part Number: mt90528ag2
• Description: 28-port Primary Rate Circuit Emulation Aal1 Sar
• Manufacturer: Zarlink Semiconductor

Figure 69 illustrates the connections from the external pins of the UTOPIA interface to an ATM device, when the
MT90528 device is operating in PHY mode.
ATM Device
Note 1: The ATM device is not required to drive the UTOPIA clock. The UTO_IN_CLK and UTO_OUT_CLK pins of
the MT90528 can either be inputs or outputs.
Note 2: When in PHY mode, UTO_IN_ENBATM_CLAVPHY, UTO_IN_SOC, UTO_OUT_ENBATM_CLAVPHY and
UTO_OUT_SOC should be pulled down. It is also recommended to pull up UTO_IN_CLAVATM_ENBPHY and
UTO_OUT_CLAVATM_ENBPHY.
