The AD9508 provides clock fanout capability in a design thatemphasizes low jitter to maximize system performance. Thisdevice benefits applications like clocking data converters withdemanding phase noise and low jitter requirements.
There are four independent differential clock outputs, each withvarious types of logic levels available. Available logic typesinclude LVDS (1.65 GHz), HSTL (1.65 GHz), and 1.8 V CMOS(250 MHz). In 1.8 V CMOS output mode, the differential outputbecomes two CMOS single-ended signals. The CMOS outputsare 1.8 V logic levels, regardless of the operating supply voltage.
Each output has a programmable divider that can be bypassedor be set to divide by any integer up to 1024. In addition, theAD9508 supports a coarse output phase adjustment betweenthe outputs.
The device can also be pin programmed for various fixedconfigurations at power-up without the need for SPI or I2C programming.
The AD9508 is available in a 24-lead LFCSP and operates froma either a single 2.5 V or 3.3 V supply. The temperature range is−40°C to +85°C.
Applications
- Low jitter, low phase noise clock distribution
