Clock buffer and divider

7 August 2013 Analogue, Mixed Signal, LSI

The AD9508 from Analog Devices is a clock buffer and divider IC that combines high speed, very low jitter (41 fs across the 12 kHz to 20 MHz band) and selectable division capability. The 1,65 GHz device is designed for communications, instrumentation, defence and aerospace equipment that requires ultra-high-speed data conversion with optimum signal-to-noise ratio performance.

The IC has four dedicated output dividers with bus-programmable division (integers up to 1024) and phase delay, and automatic synchronisation. The dividers also have pin-strapping capability for hardwired programming at system power-up.

The AD9508 supports up to four differential or eight single-ended outputs and three logic levels: LVDS (1,65 GHz), HSTL (1,65 GHz) and CMOS (250 MHz).
