The CYW320OXC-4T is a fully integrated clock and timing device developed by Cypress Semiconductor for use as a low-cost clock and timing solution. This device enables ultra-low power operations in automotive, multimedia, consumer, and portable electronic products.

CYW320OXC-4T’s primary application fields are automotive, consumer, multimedia, and portable applications. This device integrates multiple programmable clock generators, frequency synthesizers, phase-locked loops (PLLs). It is suitable for audio, video and high-speed serial interface such as UART, I2C, SPI, and Ethernet. Additionally, it features a low cost solution with advanced features like jitter attenuator, drift control, and automatic audio de-emphasis.

The Cypress CYW320OXC-4T features an on-chip programmable clock generator and frequency synthesizer that allows users to adapt their clock and timing solutions to the needs of their applications. The clock generator consists of digital tunable oscillators (DTOs) and quartz crystal oscillators (XOs). The device supports a wide range of digital modulation schemes, allowing for a low-cost, reliable solution for low-power digital designs.

The device is equipped with phase-locked loops (PLLs), allowing for absolute clock synchronization and phase control. It also supports fractional-N phase-locked loop configurations, meaning it is able to precisely synchronize its clock output with ultra-low jitter. This makes it ideal for use in automotive and portable applications where precise clock synchronization is required.

The CYW320OXC-4T also features an on-chip jitter attenuator, giving it the ability to reduce system jitter by up to 50%. This allows the device to be used in system designs requiring low-jitter clocks. Additionally, it has an on-chip drift control feature that helps reduce power consumption and improves system stability.

The CYW320OXC-4T supports both input and output de-emphasis. Input de-emphasis is used to reduce high-frequency signal error in signal paths and output de-emphasis allows for AUDIO bypassing in digital systems. This device can be programmed through an I2C interface and its integrated oscillators, jitter attenuators and drift control features offer a reliable, low-cost solution for clock generation and synchronization.

In summary, the CYW320OXC-4T is an ideal device for low power operations used in automotive, consumer, multimedia, and portable applications. It features on-chip programmable clock generators, frequency synthesizers, PLLs, jitter attenuators, and drift control. It allows for precise synchronization of digital signals and supports input and output de-emphasis. The device can be programmed through an I2C interface and is equipped with advanced features like jitter attenuation, drift control, and automatic audio de-emphasis.
