FemtoClock® Crystal-to-LVPECL 375MHz
Frequency Margining Synthesizer
843201-375
DATASHEET
GENERAL DESCRIPTION
FEATURES
The 843201-375 is a low phase-noise frequency margining
synthesizer. In the default mode, the device nominally generates a
375MHz LVPECL output clock signal from a 25MHz crystal input.
There is also a frequency margining mode available where the
device can be configured, using control pins, to vary the output
frequency up or down from nominal by 5%. The 843201-375 is
provided in a 16-pin TSSOP package.
• One 375MHz nominal LVPECL output
• Crystal oscillator interface designed for 25MHz, 18pF parallel
resonant crystal
• Output frequency can be varied ± 5% from nominal
• VCO range: 700MHz - 800MHz
• RMS phase jitter @ 375MHz, using a 25MHz crystal
(12kHz - 20MHz): 0.72ps (typical) @ 3.3V
• Output supply modes

FUNCTIONAL DESCRIPTION
The 843201-375 features a fully integrated PLL and therefore
requires no external components for setting the loop bandwidth.
A 25MHz fundamental crystal is used as the input to the on chip
oscillator. In regular mode, the 25MHz crystal frequency is applied
directly to the phase detector. In frequency margining mode, the
25MHz crystal frequency is divided by 2 and a 12.5MHz reference
frequency is applied to the phase detector. The VCO of the PLL
operates over a range of 700MHz to 800MHz. The output of the M
divider is also applied to the phase detector. The default mode for
the 843201-375 is a nominal 375MHz output. The nominal output
frequency can be changed by placing the device into the margining
mode using the mode pin and using the margin pin to change the M
feedback divider. Frequency margining mode operation occurs when
the MODE input is HIGH. The phase detector and the M divider force
the VCO output frequency to be M times the reference frequency by
adjusting the VCO control voltage. The output of the VCO is scaled by
an output divider prior to being sent to the LVPECL output buffer. The
divider provides a 50% output duty cycle. The relationship between
the crystal input frequency, the M divider, the VCO frequency and
the output frequency is provided in Table 1. When changing back
from frequency margining mode to nominal mode, the device will
return to the default nominal configuration described above.

TERMINATION FOR 3.3V LVPECL OUTPUT
The clock layout topology shown below is a typical termination for
LVPECL outputs. The two different layouts mentioned are recommended only as guidelines.
transmission lines. Matched impedance techniques should be used
to maximize operating frequency and minimize signal distortion.
Figures 2A and 2B show two different layouts which are recommended only as guidelines. Other suitable clock layouts may exist
and it would be recommended that the board designers simulate
to guarantee compatibility across all printed circuit and clock component process variations.
The differential outputs are low impedance follower outputs that
generate ECL/LVPECL compatible outputs. Therefore, terminating
resistors (DC current path to ground) or current sources must be
used for functionality. These outputs are designed to drive 50Ω

POWER CONSIDERATIONS
This section provides information on power dissipation and junction temperature for the 843201-375.
Equations and example calculations are also provided.
1. Power Dissipation.
The total power dissipation for the 843201-375 is the sum of the core power plus the power dissipated due to loading.
The following is the power dissipation for VCC = 3.3V + 5% = 3.465V, which gives worst case results.
NOTE: Please refer to Section 3 for details on calculating power dissipated due to loading.
•
•
Power (core)MAX = VCC_MAX * IEE_MAX = 3.465V * 108mA = 374.2mW
Power (outputs)MAX = 30mW/Loaded Output pair
Total Power_MAX (3.465V) = 374.2mW + 30mW = 404.2mW
2. Junction Temperature.
Junction 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 = θJA * Pd_total + TA
Tj = Junction Temperature
θJA = 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 θJA must be used. Assuming 0 air flow
and a multi-layer board, the appropriate value is 99.9°C/W per Table 8 below.
Therefore, Tj for an ambient temperature of 70°C with all outputs switching is:
70°C + 0.404W * 99.9°C/W = 110°C. This is well 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).

3. Calculations and Equations.
The purpose of this section is to derive the power dissipated into the load.
LVPECL output driver circuit and termination are shown in Figure 5.
FIGURE 5. LVPECL DRIVER CIRCUIT AND TERMINATION
To calculate power dissipation due to loading, use the following equations which assume a 50Ω load, and a termination
voltage of VCCO- 2V.
•
For logic high, VOUT = VOH_MAX = VCCO_MAX – 0.9V
(VCCO_MAX - VOH_MAX) = 0.9V
•
For logic low, VOUT = VOL_MAX = VCCO_MAX – 1.7V
(VCCO_MAX - VOL_MAX) = 1.7V
Pd_H is power dissipation when the output drives high.
Pd_L is the power dissipation when the output drives low.
Pd_H = [(VOH_MAX – (VCCO_MAX - 2V))/RL] * (VCCO_MAX - VOH_MAX) = [(2V - (VCCO_MAX - VOH_MAX))/RL] * (VCCO_MAX - VOH_MAX) =
[(2V - 0.9V)/50Ω] * 0.9V = 19.8mW
Pd_L = [(VOL_MAX – (VCCO_MAX - 2V))/RL] * (VCCO_MAX - VOL_MAX) = [(2V - (VCCO_MAX - VOL_MAX))/RL] * (VCCO_MAX - VOL_MAX) =
[(2V - 1.7V)/50Ω] * 1.7V = 10.2mW
Total Power Dissipation per output pair = Pd_H + Pd_L = 30mW
