DATASHEET
General Description
Features
The IDT8N4DV85 is a LVDS Dual-Frequency Programmable VCXO
with very flexible frequency and pull-range programming capabilities.
The device uses IDT’s fourth generation FemtoClock® NG
technology for an optimum of high clock frequency and low phase
noise performance. The device accepts 2.5V or 3.3V supply and is
packaged in a small, lead-free (RoHS 6) 6-lead ceramic 5mm x 7mm
x 1.55mm package.

Principles of Operation
The block diagram consists of the internal 3RD overtone crystal and
oscillator which provide the reference clock fXTAL of 114.285MHz.
The PLL includes the FemtoClock NG VCO along with the
Pre-divider (P), the feedback divider (M) and the post divider (N). The
P, M, and N dividers determine the output frequency based on the
fXTAL reference. The feedback divider is fractional supporting a huge
number of output frequencies. Internal registers are used to hold up
to two different factory pre-set configuration settings. The
configuration is selected via the FSEL pin. Changing the FSEL
control results in an immediate change of the output frequency to the
selected register values. The P, M, and N frequency configurations
support an output frequency range 15.476MHz to 866.67MHz and
975MHz to 1,300MHz.

Frequency Configuration
An order code is assigned to each frequency configuration and the
VCXO pull-range programmed by the factory (default frequencies).
For more information on the available default frequencies and order
codes, please see the Ordering Information Section in this document.
For available order codes, see the FemtoClock NG Ceramic-Package
XO and VCXO Ordering Product Information document.
The devices use the fractional feedback divider with a delta-sigma
modulator for noise shaping and robust frequency synthesis
capability. The relatively high reference frequency minimizes phase
noise generated by frequency multiplication and allows more efficient
shaping of noise by the delta-sigma modulator. The output frequency
is determined by the 2-bit pre-divider (P), the feedback divider (M)
and the 7-bit post divider (N). The feedback divider (M) consists of
both a 7-bit integer portion (MINT) and an 18-bit fractional portion
(MFRAC) and provides the means for high-resolution frequency
generation. The output frequency fOUT is calculated by:
1
MFRAC + 0.5

Applications Information
Recommendations for Unused Input Pins
Inputs:
LVCMOS Pins
All control pins have internal pulldowns; additional resistance is not
required but can be added for additional protection. A 1k resistor
can be used.
LVDS Driver Termination
For a general LVDS interface, the recommended value for the
termination impedance (ZT) is between 90 and 132. The actual
value should be selected to match the differential impedance (Z0) of
your transmission line. A typical point-to-point LVDS design uses a
100 parallel resistor at the receiver and a 100 differential
transmission-line environment. In order to avoid any
transmission-line reflection issues, the components should be
surface mounted and must be placed as close to the receiver as
possible. IDT offers a full line of LVDS compliant devices with two
types of output structures: current source and voltage source. The
LVDS
Driver
standard termination schematic as shown in Figure 1A can be used
with either type of output structure. Figure 1B, which can also be
used with both output types, is an optional termination with center tap
capacitance to help filter common mode noise. The capacitor value
should be approximately 50pF. If using a non-standard termination, it
is recommended to contact IDT and confirm if the output structure is
current source or voltage source type. In addition, since these
outputs are LVDS compatible, the input receiver’s amplitude and
common-mode input range should be verified for compatibility with
the output.

Power Considerations
This section provides information on power dissipation and junction temperature for the IDT8N4DV85.
Equations and example calculations are also provided.
1.
Power Dissipation.
The total power dissipation for the IDT8N4DV85 is the sum of the core power plus the analog power plus the power dissipated in the load(s).
The following is the power dissipation for VCC = 3.3V + 5% = 3.465V, which gives worst case results.
•
Power (core)MAX = VCC_MAX * ICC_MAX = 3.465V * 175mA = 606.375mW
•
2. Junction Temperature.
Junction temperature, Tj, is the temperature at the junction of the bond wire and bond pad directly affects the reliability of the device. The
maximum recommended junction temperature is 125°C. Limiting the internal transistor junction temperature, Tj, to 125°C ensures that the bond
wire and bond pad temperature remains below 125°C.
The equation for Tj is as follows: Tj = JA * Pd_total + TA
Tj = Junction Temperature
JA = Junction-to-Ambient Thermal Resistance
Pd_total = Total Device Power Dissipation (example calculation is in section 1 above)
TA = Ambient Temperature
In order to calculate junction temperature, the appropriate junction-to-ambient thermal resistance JA must be used. Assuming no air flow and
a multi-layer board, the appropriate value is 49.4°C/W per Table 6 below.
Therefore, Tj for an ambient temperature of 85°C with all outputs switching is:
85°C + 0.606W * 49.4°C/W = 114.9°C. This is below the limit of 125°C.
This calculation is only an example. Tj will obviously vary depending on the number of loaded outputs, supply voltage, air flow and the type of
board (multi-layer).
