Cypress Semiconductor Corp CY29946AXIT
- Part Number:
- CY29946AXIT
- Manufacturer:
- Cypress Semiconductor Corp
- Ventron No:
- 2974418-CY29946AXIT
- Description:
- IC CLK BUFFER 2:10 200MHZ 32TQFP
- Datasheet:
- CY29946AXIT
Description
The CY29946 is a lowvoltage 200MHz clock distribution buffer that can select one of two LVCMOS/LVTTLcompatible input clocks. These clock sources can be used to provide for test clocks as well as the primary system clocks. All other control inputs are LVCMOS/LVTTL compatible. The 10 outputs are LVCMOS or LVTTL compatible and can drive 50 Ω series or parallel terminated transmission lines. For series terminated transmission lines, each output can drive one or two traces giving the device an effective fanout of 1:20.
The CY29946 is capable of generating 1x and 1/2x signals from a 1x source. These signals are generated and retimed internally to ensure minimal skew between the 1x and 1/2x signals. SEL(A:C) inputs allow flexibility in selecting the ratio of 1× to 1/2 outputs.
The CY29946 outputs can also be threestated via MR/OE# input. When MR/OE# is set HIGH, it resets the internal flipflops and threestates the outputs.
