STMUX1800EQTR datasheet by STMicroelectronics

STMUX1800EQTR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the STMUX1800EQTR?
  The maximum operating frequency of the STMUX1800EQTR is 100 MHz, but it can be limited by the capacitance of the load and the signal integrity of the PCB.
• How do I ensure signal integrity when using the STMUX1800EQTR?
  To ensure signal integrity, it is recommended to use a low-impedance PCB, minimize trace lengths, and use termination resistors at the receiver end. Additionally, the use of a clock signal with a fast rise time and a low jitter can also help to improve signal integrity.
• What is the power consumption of the STMUX1800EQTR?
  The power consumption of the STMUX1800EQTR depends on the operating frequency, input voltage, and output load. According to the datasheet, the typical power consumption is around 15 mA at 100 MHz with a 3.3V supply voltage and a 10 pF load.
• Can I use the STMUX1800EQTR with a 1.8V supply voltage?
  Yes, the STMUX1800EQTR can operate with a supply voltage as low as 1.8V, but the maximum operating frequency may be limited to 50 MHz. It is recommended to consult the datasheet for specific operating conditions and limitations.
• How do I configure the STMUX1800EQTR for differential signaling?
  To configure the STMUX1800EQTR for differential signaling, the DIFF pin should be tied to VCC, and the IN+ and IN- pins should be connected to the differential signal sources. The OUT+ and OUT- pins will then output the differential signal.
