a. See “HSTL Differential Input Levels” in Figure 5
b. VDIF specifies the input differential voltage.
c. VCM is the maximum allowable range of VTR - ((VTR - VCP)/2). VTR is true input signal, VCP is its complementary input signal.
d. VCMR is the difference from VCC and the crosspoint of the differential input signal. Normal operation is obtained when the “high” input is
within the VCMR range and the input swing lies within the VPP specification.
e. LVPECL input level specifications will vary 1:1 with VCC.
