• Manufacturer Part Number: PEB20571
• Description: ICs for Communications
• Manufacturer: INFINEON [Infineon Technologies AG]

The IOMU meets the IOM-2 interface timing specifications as described below.
Single Data Rate DCL Mode
• Serial transmission via DD0/DD1 with every DCL rising edge
• Sampling of the incoming serial data (DU0/DU1) with every DCL falling edge
• Sampling FSC with every DCL falling edge. Sampling of FSC = 1 after sampling of
Double Data Rate DCL Mode
• Two DCL cycles per bit (the bits are aligned to the frame start)
• Serial transmission via DU0/1 with every second DCL rising edge.
• Sampling of incoming serial data (DD0/1) with the second DCL falling edge of each bit.
• Sampling of FSC every DCL falling edge. Sampling of FSC = 1 after sampling of
Figure 4-4 shows the IOM-2 interface timing with single and double rate DCL. For more
details refer to the general IOM-2 interface description.
