9.3 Feature Description

The LMK1D1208P is a low additive jitter LVDS fan-out buffer that can generate up to four copies of two selectable LVPECL, LVDS, HCSL, CML, or LVCMOS inputs. The LMK1D1208P can accept reference clock frequencies up to 2 GHz while providing low output skew.

Table 9-1 lists the LMK1D1208P outputs divided into two banks.

Table 9-1 Output Bank Mapping
BANKCLOCK OUTPUTS
0OUT0, OUT1, OUT2, OUT3
1OUT4, OUT5, OUT6, OUT7

Apart from providing a very low additive jitter and low output skew, the LMK1D1208P has an input select pin (IN_SEL) and an output amplitude control pin (AMP_SEL).
