Abstract
A dual purpose serializer/de-serializer (SerDes) for point-to-point and point-to-multipoint communication. A configurable SerDes can be designed to operate in one of a plurality of operating modes. Selection between the plurality of operating modes can be based on information received via a management interface. In one example, the various operating modes can be defined with different locking times and jitter characteristics.
Claims17
A serializer/de-serializer method, comprising:
- storing, via an operation mode management interface, a parameter in a register of a serializer/de-serializer;
- configuring, based on said parameter stored in said register, a clock recovery module of said serializer/de-serializer to operate in one of a first operating mode and a second operating mode, said first and second operating modes being characterized by different locking time periods;
- and
- recovering an incoming embedded clock from a received signal using said configured operating mode.
1 more element
A serializer/de-serializer, comprising:
- a clock recovery module that is configurable to operate in a first mode capable of locking onto an incoming embedded clock within a first locking time period, and in a second mode capable of locking onto an incoming embedded clock within a second locking time period shorter than said first locking time period, wherein a configuration of said clock recovery module is based on one or more parameters retrieved from a configuration register.
A serializer/de-serializer, comprising:
- a configuration register;
- a clock recovery module that is configured at power up to operate in a selected one of a plurality of operating modes in accordance with one or more parameters that are retrieved from said configuration register, wherein at least two of said pluralitv of operating modes have different locking time for recovering an embedded clock.
