Pl tronics, Inc.

19013 36th Ave. W, Suite H Lynnwood, WA 98036 USA

Manufacturer of High Quality Frequency Control Products

LV7645D LVDS Series

Low Voltage Differential Signal Output with Enable / Disable

–

80.00 MHz 212.50 MHz

6 Pad Leadless Surface Mount Clock Oscillator

Consult factory for higher frequencies

Standard Specifications

Overall Frequency Stability

± 50 PPM, ± 25 PPM and ± 20 PPM over Operating Temp. Range

Operating Temperature Range 0 to +80°C is standard, can be extended to - 40 to +85°C

Operable Supply Voltage (Vcc) 3.3 V ± 5% standard, 2.5 V ± 5% also available

High Level Output Voltage

Low Level Output Voltage

1.43 V typical and 1.60 V maximum with output enabled (100 ohm load, R1 = 50 ohms) See Test circuit #6

0.90 V minimum and 1.10 V typical with output enabled (same conditions as above)

Differential Output Voltage

Differential Output Error

Offset Voltage

247 mV minimum, 330 mV typical and 454 mV maximum with output enabled (same conditions as above)

50 mV maximum with output enabled (same conditions as above)

1.125 V minimum, 1.25 V typical and 1.375 V maximum with output enabled (same as above)

Offset Voltage Error

Output Leakage Current

Supply Current (Icc)

Symmetry (DC1)

Symmetry (DC2)

Rise and Fall Time (Tr & Tf)

RMS Jitter

50 mV maximum with output enabled (same as above)

10 uA maximum with output disabled

35 mA typical and 47 mA maximum with output enabled, 30 uA maximum with output disabled

45/55% measured at crossing point 0°C <= Ta <= 70°C, 40/60% measured at Ta < 0°C and Ta > 70°C

45/55% measured at 50% of output swing 0°C <= Ta <= 70°C, 40/60% measured at 50% of output swing

1.5 nS max at 20% to 80% output swing (100 ohm load) See Test circuit #6 and Waveform #2

1.5 pS max at12 kHz to 20 MHz from the output

Enable / Disable Pin:

The Enable / Disable pin has an internal pull up and if the pin is not connected the oscilaltor is enabled. Pletronics strongly recommends

connecting the Enable / Disable pin to Vcc, if the oscillator is to be enabled at all times. In the disable condition, the output becomes a

high impedance and the internal oscillator circuit is inhibited (the internal circuit is stopped).

High Level Input Voltage

Low Level Input Voltage

High Level Input Current

Low Level Input Current

Output Enable Time

0.7 Vcc minimum at Enable / Disable Pin

0.3 Vcc maximum at Enable / Disable Pin

-20 uA maximum at Enable / Disable Pin = 0.7 Vcc

-200 uA maximum at Enable / Disable Pin = 0 V

200 nS maximum at output enable or 1 mS maximum at output enabled and stable

200 nS maximum at output disable

Output Disable Time

Part Numbering Guide

Portions of the part number that appear after the frequency may not be marked on part (C of C provided)

LV76 45 D V - 100.0M - XXX (Internal Code or blank)

Packaging

Tube or

16mm tape

8mm pitch

Model

Frequency in MHz

LV76 = E/D Pin 1

LV78 = E/D Pin 2

Special Specifications (choose all that apply)

E: Extended Operating Temp Range (-40 to +85°C)

V: Supply Voltage of 3.3 volts ±5%

W: Supply Voltage of 2.5 volts ±5%

Frequency Stability

45 = ± 50 PPM

44 = ± 25 PPM

20 = ± 20 PPM

Consult factory for available frequencies and specs. Not all options available for all frequencies. A special part number may be assigned.

Frequency Stability is inclusive of frequency shifts due to calibration, temperature, supply voltage, shock, vibration and load
