JAJSN78A October 2021 – January 2022 LMK1D2106 , LMK1D2108
PRODUCTION DATA
The output banks of the LMK1D210x can be selected through the control pin (see Table 8-2). Unused inputs can be left floating to reduce overall component cost. Both AC- and DC-coupling schemes can be used with the LMK1D210x to provide greater system flexibility.
| EN | CLOCK OUTPUTS |
|---|---|
| 0 | All bank outputs disabled (static logic "0") |
| 1 | Bank 0 outputs enabled and Bank 1 outputs disabled |
| OPEN | All bank outputs enabled |
The output amplitude of the banks of the LMK1D210x can be selected through the amplitude selection pin (see Table 8-3). The higher output amplitude mode (boosted swing LVDS mode) can be used in applications which require higher amplitude either for better noise performance (higher slew rate) or if the receiver has swing requirements which the standard LVDS swing cannot meet.
| AMP_SEL | OUTPUT AMPLITUDE (mV) |
|---|---|
| 0 | Bank 0: boosted LVDS swing (500 mV) Bank 1: standard LVDS swing (350 mV) |
| OPEN | Bank 0: standard LVDS swing (350 mV) Bank 1: standard LVDS swing (350 mV) |
| 1 | Bank 0: boosted LVDS swing (500 mV) Bank 1: boosted LVDS swing (500 mV) |
