Mingjiada Electronics Supply ADI AD9522 And AD9520 Series CMOS Output Clock Generator

Shenzhen Mingjiada Electronics Co., Ltd. — with many years of specialised experience in the electronic components sector, we are a long-standing supplier of the [ADI] AD9522 and AD9520 series CMOS output clock generators. These devices integrate a high-performance PLL and a 2.5 GHz VCO, support multi-output configurations, and can flexibly provide LVPECL, LVDS and CMOS clock outputs. They are widely used in communications, networking, data acquisition, instrumentation and industrial control applications.

Product Overview
The AD9520 / AD9522 are multi-output clock generators launched by ADI, featuring an integrated VCO and a programmable PLL, and providing 12 output channels. Each output channel can be independently configured as an LVPECL, LVDS or CMOS output; when configured as CMOS, each channel can be expanded to two CMOS outputs, thus providing up to 24 CMOS clock outputs, making them ideal for systems requiring multi-channel, low-jitter clock distribution.
The AD9520 series incorporates an EEPROM to store user configurations and enable automatic loading upon power-up; the AD9522 series does not include an EEPROM and is programmed via an SPI interface. Both support dual reference inputs, automatic/manual switching and hold mode, ensuring system clock continuity in the event of a reference clock failure.

Key Features
