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

Figure 68 below illustrates the connections from the external pins of the UTOPIA interface to a PHY device, when
the MT90528 is operating in ATM mode.
PHY Device
Note 1: The MT90528 does not have 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 ATM mode, UTO_IN_CLAVATM_ENBPHY, UTO_IN_SOC, UTO_OUT_CLAVATM_ENBPHY and
UTO_OUT_SOC should be pulled down. It is also recommended to pull up UTO_IN_ENBATM_CLAVPHY and
UTO_OUT_ENBATM_CLAVPHY.
