PRODUCTION DATA
In many cases, not all pins are used. Table 8-1 lists the recommendations on how to handle these unused pins.
PINS | TREATMENT |
---|---|
All VCC Pins | These pins must always be connected to the power supply. If the block that powers these VCC pins (as implied by the pin name) is not used, then the bypassing can be minimized or eliminated. |
SYNC_P / SYNC_N |
|
CLKIN_P / CLKIN_N | If driving single-ended input, the complementary input must have an AC-coupling capacitor and 50 Ω to ground. |
CLKOUTx_P / CLKOUTx_N | If not used, connect a AC-coupling capacitor and 50 Ω to ground. |
AUXCLKOUT_P / AUXCLKOUT_N | If these pins are unused, connect the pins to ground with a 1-kΩ resistor. |
CLKx_EN |
|
MUXSEL, DIVSELx | If these pins are unused, connect these pins to ground with a 1-kΩ resistor. |
