20120326795, Dec 27, 2012

Filed:

Jun 27, 2011

Appl. No.:

13/170106

Inventors:

Janice Chiu - Tustin CA, US
Srinivas Badam - Irvine CA, US

Assignee:

BROADCOM CORPORATION - IRVINE CA

International Classification:

H03L 7/00
H03L 7/08

US Classification:

331 17, 327157

Abstract:

A technique to use a two-step calibration procedure to calibrate a voltage controlled oscillator (VCO) of a phase-locked loop. The first calibration step is an open-loop calibration procedure in which a control voltage of the VCO is temperature compensated and the VCO is tuned using a search routine to generate a corresponding output frequency based on the control voltage. The second step is a closed-loop calibration procedure to adjust the tuning components of the VCO to correct for a 1 LSB error.

Abstract:

A serial transceiver that includes programmable distributed data processing is provided. The serial transceiver can include an ingress channel that receives serial ingress data and an egress channel that transmits serial egress data. The serial transceiver can also include first and second layers that are one and another of a transport layer, a link layer, or a physical layer (PHY). The first and second layers can include elements that process the ingress data and the egress data. The serial transceiver can also include a programmable controller, a first interconnect that connects the programmable controller to the first layer, and a second interconnect that connects the programmable controller to the second layer. The programmable controller can send first data via the first interconnect to the first layer, and the first data can be processed by one of the first layer elements.
