Data Sheet
2
Zarlink Semiconductor Inc.
The MT90866 also offers a sub-rate switching configuration which allows 2-bit wide 16kb/s or 4-bit wide 32 kb/s
data channels to be switched within the device.
The device has features that are programmable on a per-stream or a per-channel basis including message mode,
input delay offset, output advancement offset, direction control, and high impedance output control.
The MT90866 supports all three of the H.110 specification required clocking modes: Primary Master, Secondary
Master and Slave.
