49FCT20805PYGI8 - Renesas Electronics

Description: The FCT20805 is a 2.5 volt clock driver built using advanced CMOS technology. The device consists of two banks of drivers, each with a 1:5 fanout and its own output enable control. The device has a "heartbeat" monitor for diagnostics and PLL driving. The MON output is identical to all other outputs and complies with the output specifications in this document. The FCT20805 offers low capacitance inputs. The FCT20805 is designed for high speed clock distribution where signal quality and skew are critical. The

49FCT20805PYGI8 Frequently Asked Questions (FAQs)

  • The 49FCT20805PYGI8 can operate from -40°C to 85°C (industrial temperature range) and -40°C to 125°C (extended temperature range) with reduced performance.
  • To ensure signal integrity, use a 22-ohm series resistor on each output pin, and consider using a 100-ohm termination resistor on the receiving end. Additionally, use a low-inductance PCB design and minimize trace lengths.
  • Power up the device in the following sequence: VCC, then VCCQ, and finally the input signals. This ensures proper device initialization and prevents latch-up.
  • To prevent bus contention, use open-drain or tri-state outputs, and ensure that only one device drives the bus at a time. You can also use a bus arbiter or a multiplexer to manage bus access.
  • The maximum current draw for the 49FCT20805PYGI8 is 100 mA per output pin, with a total device current of 500 mA. Ensure your power supply can provide sufficient current to meet these requirements.
