S19233 – 10 G Ethernet/Fibre Channel/SONET/SDH
Dual CDR
I2C BUS
S19233 uses a simple bi-directional two-wire bus for
efficient inter-IC control. All register controlled features
and functions are programmed via the I

The S19233 has a unique address on the bus
and a slave configuration at all times.
Only two bus lines are required; a serial Data
Input/Output line (SDA) and a Clock line (SCL).
