CY23EP09SXI-1T is a frequency synthesizer from the Clock/Timing lineup of Cypress Semiconductor Corporation. A frequency synthesizer is an electronic device that produces a signal of a certain frequency without any external oscillator. A frequency synthesizer by its nature requires a relatively low amount of power to operate and creates very precise frequency outputs. The CY23EP09SXI-1T is well-suited for applications such as frequency multiplication, sampling, clock recovery, and jitter attenuation of high speed serial data streams.

The CY23EP09SXI-1T has integrated Phase-Locked Loop (PLL) circuitry, which helps in generating precise frequency outputs. In PLL-based circuits, an externally fed clock signal frequency is compared to the output frequency of an oscillating stage such as an LC or RC oscillator. The PLL compares these frequencies in order to base its output frequency signals. The CY23EP09SXI-1T has a wide range of input frequencies (500 kHz to 1250 MHz) and can output signals with frequencies from 20Khz to 4GHz.

The CY23EP09SXI-1T is compatible for integration into a wide variety of applications. radio receivers, cellular phones, DSPs, and base stations. in addition to these applications, the device is also well-suited for clock recovery, frequency vending, and jitter attenuation in high speed serial data streams such as, 10/40 GbE, HDMI and USB.

The CY23EP09SXI-1T is designed with a flexible architecture consisting of the PLL, Charge Pump, and VCO. The amount of current required to charge the PLL is user-adjustable using an external resistor. The device requires only a +1.2V supply voltage to operate and provides low-power consumption (95mW). Furthermore, the device has excellent phase noise performance, with a typical phase noise of -80 dBc/Hz at 100 kHz from the carrier.

The flexibility of the CY23EP09SXI-1T allows it to be used in a wide range of applications, from simple frequency generation for low power devices to precise clock recovery for high speed serial data streams. The device is configurable for a wide range of frequencies, and is capable of providing precise frequency synthesis and low power consumption. This makes the CY23EP09SXI-1T an ideal solution for low power, precise frequency synthesis.
