The 8305AG-02LF belongs to the class of clock buffers, drivers and other related clock/timing devices. In this article, let us review the application field and working principle of the 8305AG-02LF.

As a high performance, low-power clock buffer, the 8305AG-02LF specifies support for both 400MHz and 800MHz LVDS, LVPECL and 622MHz HCSL outputs, at rail-to-rail, single-ended and differential supply configurations. It has Ten differential pairs driving up to 10 independent outputs, each output with up to 0.75 GHz of typical frequency performance. The 8305AG-02LF boasts advanced diagnostics features and a very small, 1mmx1.6mm 10-pin LFFN package. Furthermore, it has an extensive application field, ranging from consumer electronics such as laptop computers, set-top boxes, and other such space-sensitive consumer devices; to mission-critical telecom, data processing and storage systems.

When it comes to the working principle, the 8305AG-02LF’s programmable output enables Clock Retiming, Clock adjustment, Skew adjustment, Phase-Locking, phase-Shifting and Jitter Attenuation functions, making it a versatile and economical solution for wide applications. The clock inputs supports a wide variety of standard signals, from LVPECL, LVDS and HCSL compatible to a differential CMOS input and a single-ended HCSL input. The LVDS and LVPECL outputs have extremely tight duty-cycle control, significantly reducing the duty cycle distortion of input clock pulse-width. This helps designers to address signal integrity issues and also reduces power emission, ultimately improving signal integrity.

The 8305AG-02LF has an adjustable frequency range on the outputs, allowing users to determine the frequency of the output signal to a higher level of accuracy. It also has superb differential pair level control functionality which can be used to adjust both clock and data lines to their specified levels. Additionally, the data delay adjustment feature enables the clock source to be moved ahead or behind the data line in the system to improve system timing latency.

The 8305AG-02LF can be programmed using its built-in onboard MCU, and it supports five operating modes, selectable via a MCU command. The modes are as follows: Free Running, Single Cycle, Half Cycle, Quarter Cycle and Cycle (4/4). The 8305AG-02LF further offers an innovative long-term jitter-attenuator, which can reduce jitter in long-term noisy clock signals to an extremely low level.

To sum up, the 8305AG-02LF is an excellent choice for clock buffers and drivers applications. It has a wide range of features and capabilities, making it an ideal solution for a wide range of consumer and mission-critical telecom and storage systems. Its extensive array of features also make it an economical solution, reducing power consumption and helping designers address challenging signal integrity issues. With its advanced diagnostics and reliable performance, the 8305AG-02LF is a dependable and affordable clock/timing solution.
