idt8SLVP1102I datasheet low phase noise, 1-to-2, 3.3v, 2.5v lvpecl output fanout buffer idt8slvp1102anli march 13, 2018 6 ?2018 integrated device technology, inc. additive phase jitter the spectral purity in a band at a specific offset from the fundamental compared to the power of the fundamental is called the dbc phase noise. this value is normally expressed using a phase noise plot and is most often the specified plot in many applications. phase noise is defined as the ratio of the noise power present in a 1hz band at a specified offset from the fundamental frequency to the power value of the fundamental. this ratio is expressed in decibels (dbm) or a ratio of the power in the 1hz band to the power in the fundamental. when the required offset is specified, the phase noise is called a dbc value, which simply means dbm at a specified offset from the fundamental. by investigating jitter in the frequency domain, we get a better understanding of its effects on the desired application over the entire time record of the signal. it is mathematically possible to calculate an expected bit error rate given a phase noise plot. as with most timing specifications, phase noise measurements have issues relating to the limitations of the equipment. often the noise floor of the equipment is higher than the noise floor of the device. this is illustrated above. the device meets the noise floor of what is shown, but can actually be lower. the phase noise is dependent on the input source and measurement equipment. measured using a wenzel 156.25mhz oscillator as the input source. offset from carrier frequency (hz) ssb phase noise dbc/hz

idt8SLVP1102I datasheet low phase noise, 1-to-2, 3.3v, 2.5v lvpecl output fanout buffer idt8slvp1102anli march 13, 2018 9 ?2018 integrated device technology, inc. applications information wiring the differential input to accept single-ended levels the idt8SLVP1102I inputs can be interfaced to lvpecl, lvds, cml or lvcmos drivers. figure 1a illustrates how to dc couple a single lvcmos input to the idt8SLVP1102I. the value of the series resistance rs is calculated as the difference between the transmission line impedance and the driver output impedance. this resistor should be placed close to the lvcmos driver. to avoid cross-coupling of single-ended lvcmos signals, apply the lvcmos signals to no more than one pclk input. a practical method to implement vth is shown in figure 1b below. the reference voltage vth = v1 = v cc /2, is generated by the bias resistors r1 and r2. the bypass capacitor (c1) is used to help filter noise on the dc bias. this bias circuit should be located as close to the input pin as possible. the ratio of r1 and r2 might need to be adjusted to position the v1 in the center of the input voltage swing. for example, if the input clock swing is 2.5v and v cc = 3.3v, r1 and r2 value should be adjusted to set v1 at 1.25v. the values below apply when both the single-ended swing and v cc are at the same voltage. figure 1a. dc-coupling a single lvcmos input to the idt8SLVP1102I when using single-ended signaling, the noise rejection benefits of differential signaling are reduced. even though the differential input can handle full rail lvcmos signaling, it is recommended that the amplitude be reduced, particularly if both input references are lvcmos to minimize cross talk. the datasheet specifies a lower differential amplitude, however this only applies to differential signals. for single-ended applications, the swing can be larger, however v il cannot be less than -0.3v and v ih cannot be more than v cc + 0.3v. figure 1b shows a way to attenuate the pclk input level by a factor of two as well as matching the transmission line between the lvcmos driver and the idt8SLVP1102I at both the source and the load. this configuration requires that the sum of the output impedance of the driver (ro) and the series resistance (rs) equals the transmission line impedance. r3 and r4 in parallel should equal the transmission line impedance; for most 50 ? applications, r3 and r4 will be 100 ? . the values of the resistors can be increased to reduce the loading for slower and weaker lvcmos driver. though some of the recommended components of figure 1b might not be used, the pads should be placed in the layout so that they can be utilized for debugging purposes. the datasheet specifications are characterized and guaranteed by using a differential signal. figure 1b. alternative dc coupling a single lvcmos input to the idt8SLVP1102I
