Note : • VCCRX, VpRX, VCCTX and VpTX must supply equal voltage.
Even if either RX-PLL or TX-PLL is not used, power must be supplied to VCCRX, VpRX, VCCTX and VpTX to
keep them equal.
It is recommended that the non-use PLL is controlled by power saving function.
• Although this device contains an anti-static element to prevent electrostatic breakdown and the circuitry
has been improved in electrostatic protection, observe the following precautions when handling the device.
• When storing and transporting the device, put it in a conductive case.
• Before handling the device, confirm the (jigs and) tools to be used have been uncharged (grounded) as
well as yourself. Use a conductive sheet on working bench.
• Before fitting the device into or removing it from the socket, turn the power supply off.
• When handling (such as transporting) the device mounted board, protect the leads with a conductive
sheet.
WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
semiconductor device. All of the device’s electrical characteristics are warranted when the device is
operated within these ranges.
Always use semiconductor devices within their recommended operating condition ranges. Operation
outside these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.
