[this eliminates] the need for an external clock, creating a
self-clocking signal." (2)
Serial architecture connections consist of a single pair of transmission signals that contain an embedded clock for
self-clocking, enabling the clock speed to be easily scaled and to wrap data bits into individual packets to achieve data transfers up to 30 times faster than what parallel technology can provide.
In order to ensure reliable transmission, the TDM interface, which converts the TDM data stream to fiber, supports a
self-clocking code using a pulse-width modulation scheme that converts TDM clock information to a format suitable for fiber-optic communication.--Metrobility
Self-clocking or external clocking for tighter cutoff-frequency control is available.
Current TCP implementations are strictly
self-clocking, i.e., packet transmissions are paced by the reception of ACK packets from the receiver.
"An important differentiation is that all serial interfaces are
self-clocking, so unlike parallel SCSI, data rates can be pushed higher and higher." This adoption must be a new record for T10, which is well known for agonizing over standards acceptance.
