NORWOOD, Mass.--(Business Wire)--
Analog Devices, Inc. (NASDAQ: ADI) today introduced a clock buffer and divider
IC (integrated circuit) that combines high-speed, extremely low jitter (41 fs
across the 12-kHz to 20-MHz band) and selectable division capability. The
1.65-GHz AD9508 clock buffer is designed for communications, instrumentation,
defense and aerospace equipment that require ultra-high-speed data conversion
with optimum SNR (signal-to-noise ratio) performance. The device has four
dedicated output dividers with bus-programmable division (integers up to 1024)
and phase delay, and automatic synchronization. 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).
