The CS1810xx or CS4961xx network processor is the heart of the CobraNet interface. It
implements the network protocol stacks and performs the synchronous-to-isochronous
and isochronous-to-synchronous conversions. The network processor has a role in
sample clock regeneration and performs all interactions with the host system.
The sample clock is generated by a voltage-controlled crystal oscillator (VCXO)
controlled by the network processor. The VCXO frequency is carefully adjusted to achieve
lock with the network clock.
The Ethernet controller is a standard interface chip that implements the 100-Mbit Fast
Ethernet standard. As per Ethernet requirements the interface is transformer isolated.
