Patent number: 11967965Abstract: Clock generation circuit generating multiple divided signals satisfying respective desired offsets. A phase locked loop (PLL) is used to generate a PLL output having a frequency which is a desired multiple of that of a reference clock. The circuit divides the PLL output by a corresponding divisor to generate a corresponding divided signal, wherein each divided signal is offset from a common reference by at least an associated desired time offset. The common reference is timed with respect to the reference clock when the reference clock is available and with respect to a time reference signal otherwise. This arrangement is extended to use the internal time reference signal even for the cases where the reference clock is present by blocking the reference clock while the output systems across PLLs are aligned using the internal time reference signal to ensure desired offsets across different PLLs with a small uncertainty.Type: GrantFiled: June 14, 2022Date of Patent: April 23, 2024Assignee: Shaoxing Yuanfang Semiconductor Co., Ltd.Inventors: Raja Prabhu J, Ankit Seedher, Srinath Sridharan, Rakesh Kumar Gupta, Nitesh Naidu, Shivam Agrawal, Jeevabharathi G, Purva Choudhary

Publication number: 20230128789Abstract: An integrated circuit (IC) includes input/output (I/O) ports, each operating using one of a pair of unequal power supplies during normal operation of the IC. A lower supply of the pair of unequal power supplies is required to be used as the power supply for the I/O port when a first input signal to the IC is received from an external source on a first I/O port of the I/O ports. The voltage range of the logic excursions of the first input signal is greater than the range from a magnitude of the lower supply to a constant reference potential. A regulation loop derives a derived lower supply having a magnitude equaling that of the lower supply from the higher supply of the pair of unequal power supplies, and applies the derived lower supply on a power supply node of the first I/O port.Type: ApplicationFiled: July 18, 2022Publication date: April 27, 2023Inventors: Raja Prabhu J, Rakesh Kumar Gupta, Shuvadeep Mitra, Anurag Pulincherry, Ankit Seedher

Patent number: 11588489Abstract: A phase-locked loop (PLL) provided according to an aspect of the present disclosure includes a phase detector, a low-pass filter, an oscillator, an output block and a phase locking block. The oscillator generates an intermediate clock and the output block generates each of successive cycles of a feedback clock on counting a pre-determined number of cycles of the intermediate clock. The phase locking block, upon detecting the PLL being out of phase-lock, controls the operation of the output block to obtain phase-lock in the PLL within two cycles of the input clock from the time of detection of the PLL being out of phase-lock.Type: GrantFiled: May 10, 2022Date of Patent: February 21, 2023Assignee: Shaoxing Yuanfang Semiconductor Co., Ltd.Inventors: Rakesh Kumar Gupta, Nitesh Naidu, Raja Prabhu J, Srinath Sridharan, Ankit Seedher, Shivam Agrawal
