IDT, Integrated Device Technology Inc 840S05AYILFT

Description
The 840S051 is a five-output LVCMOS/LVTTL Frequency Synthesizer that accepts crystal or single-ended reference clock inputs. It uses a 25MHz parallel resonant crystal to generate 33.33MHz-166.67MHz clock signals, replacing solutions requiring multiple oscillators and fan-out buffers. The device supports output slew rate control with two slew select pins (SLEW[1:0]). The VCO operates at a frequency of 2GHz. The device has two output banks, Bank A with two 33.33MHz - 166.67MHz LVCMOS/LVTTL outputs and Bank B with two 33.33MHz - 166.67MHz LVCMOS/LVTTL outputs. The two banks have their own dedicated frequency select pins and can be independently set for frequencies in the ranges mentioned above. Designed for networking and industrial applications, the 840S051 can also drive the high-speed clock inputs of communication processors, DSPs, switches, and bridges.
