9.3 Feature Description

The LMK1D121x is a low additive jitter LVDS fan-out buffer that can generate up to 12 (LMK1D1212) or 16 (LMK1D1216) copies of two selectable LVPECL, LVDS, LP-HCSL, HCSL, or LVCMOS inputs. The LMK1D121x can accept reference clock frequencies up to 2 GHz while providing low output skew.

Table 9-2 lists the LMK1D1212 and LMK1D1216outputs divided into two banks.

Table 9-1 Output Bank
BankLMK1D1212LMK1D1216
0OUT0 to OUT5OUT0 to OUT7
1OUT6 to OUT11OUT8 to OUT15

Apart from providing a very low additive jitter and low output skew, the LMK1D121x has an input select pin (IN_SEL) and an output amplitude control pin (AMP_SEL).
