Abstract: Intelligent lead-acid battery system capable of monitoring a parameter (e.g., voltage, temperature) of one or more battery cells of a lead-acid battery. In one implementation, the battery system includes a housing having a cells compartment, a battery monitoring system (BMS) compartment, and a wall disposed between the cells compartment and the BMS compartment. A first post and a second post are associated with a battery cell. The first post and the second post protrude through the wall between the cells compartment to the BMS compartment. A voltage sensor electrically couples to the first post and the second post to monitor the voltage of the battery cell. A temperature sensor can couple to the first or second or both posts. The intelligent AGM battery system can predict the battery module's state of health, state of charge, module status, power capability, life expectancy, etc.

Abstract: A multiphase clock generating apparatus includes a clock generator providing an M-clock having a frequency M times that of a received reference clock. Divider circuitry is coupled to provide an alignment signal having 1/M the frequency of the M-clock. A recovery circuit recovers up to M distinct clocks from the M-clock in accordance with the alignment signal. The recovered clocks have substantially an N•180°/M phase difference from each other, wherein N?1.

Abstract: Multiphase clock generating apparatus includes a multiplexer selecting one of a generated clock and a gated generated clock as an M-clock in accordance with a halt multiplexer control. Divider circuitry provides an alignment signal corresponding to an inverted M-clock divided by M. A recovery circuit recovers up to M distinct clocks from the M-clock in accordance with the alignment signal. The recovered clocks have a 180°/M relative phase difference. A halt circuit controls the halt multiplexer control to select the gated generated clock when a selected recovered clock matches a pre-determined clock level. The halt multiplexer control is clocked by the generated clock.

Abstract: A quadrature clock generating apparatus includes a clock generator providing a double clock having a frequency that is twice that of a received reference clock. Divider circuitry is coupled to provide an alignment signal having half the frequency of the double clock. A recovery circuit recovers a first clock and a second clock from the double clock in accordance with the alignment signal. The first and second clocks have substantially a 90° phase difference.

Abstract: Quadrature clock generating apparatus includes a multiplexer selecting one of a generated clock and a gated generated clock as a double clock in accordance with a halt multiplexer control. Divider circuitry provides an alignment signal corresponding to an inverted double clock divided by two. A recovery circuit recovers first and second clocks having a 90° phase difference from the double clock in accordance with the alignment signal. A halt circuit controls the halt multiplexer control to select the gated generated clock when the alignment signal matches a pre-determined clock level. The halt multiplexer control is clocked by the generated clock.

Abstract: A method of measuring jitter includes generating a jitter pulse having a width corresponding to an amount of jitter. The jitter pulse is provided to a plurality (M) of latches serially coupled to successively trim the pulse as it propagates through the serially coupled latches. Each latch, li, provides an output bi indicative of receipt of an edge of the jitter pulse.
