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).
AD9508 1.65 GHz Clock Buffer and Divider Key Features
RMS jitter in HSTL output mode:
41 fs @ 622.08 MHz (12 kHz to 20 MHz)
72 fs @ 622.08 MHZ (20 kHz to 80 MHz)
Dividers are pin-strappable for division factors of 1,2,4,8, or 16
Outputs: 4 LVDS or HSTL; 8 single-ended CMOS
Output-to-output skew: <48 ps (LVDS)
Supply voltage: 2.5 V/3.3 V
