MK1491-09FLN - Renesas Electronics

Description: The MK1491-09 is a low cost, low jitter, high performance clock synthesizer for AMD's Geode™ GX2 processor for information appliance applications. Using patented analog Phase-Locked Loop (PLL) techniques, the device accepts a 14.318 MHz crystal input to produce multiple output clocks. It provides selectable PCI local bus clocks, 48 MHz clocks for Super I/O and USB, as well as multiple Reference outputs. The device has a power down mode to reduce power consumption.

MK1491-09FLN Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the MK1491-09FLN is -40°C to 125°C.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF and a maximum equivalent series resistance (ESR) of 1 ohm.
  • The maximum input voltage that the MK1491-09FLN can handle is 18V.
  • The output voltage of the MK1491-09FLN can be calculated using the formula: Vout = (R1 / R2) x (Vin - Vref), where R1 and R2 are the resistors in the feedback network, Vin is the input voltage, and Vref is the reference voltage.
  • The quiescent current of the MK1491-09FLN is typically around 5mA.
