Frequency Translation up to 850 MHz
VCSO based PLL for Ultra-Low Jitter
CMOS / LVDS / LVPECL Inputs compatible
Differential LVPECL or LVDS Output
CMOS Lock Detect
External Divider for Input Frequencies < 19 MHz
0°/70°C or -40°/+85°C Temperature Range

Applications
The FX-730 is a low jitter precision frequency translator
used to translate input frequencies such as 19.44,
38.88, 77.76 MHz, etc. to a binary multiple frequency as
high as 850 MHz. The FX-730’s superior jitter
performance is achieved through the PLL’s integrated
VCSO. The FX-730 is housed in a hermetically sealed
leadless surface mount package offered on tape and
reel.

It is recommended that a buffer driver is used for best noise isolation.
Do not leave the MODE pin floating, it should be set to logic 0 or ground for normal operation.
BRCLK and CBRCLK should be left floating if not used.
FIN, CFIN, BRCLK, and CBRCLK have internal pull-up/pull-down resistors and it is recommended to AC couple these inputs.

Stresses in excess of the absolute maximum ratings can permanently damage the device. Also, exposure to
these absolute maximum ratings for extended periods can adversely affect device reliability. Functional operation
is not implied at these or any other conditions in excess of those represented in the operational sections of this
data sheet. Permanent damage is also possible if any device input draws greater than 100 mA.

Reliability
VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR
reflow simulation. The FX-730 family is undergoing the following qualification tests:

Handling Precautions
Although ESD protection circuitry has been designed into the FX-730 proper precautions should be taken when
handling and mounting. VI employs a human body model (HBM), a charged-device model (CDM), and machine
model (MM) for ESD susceptibility testing and design protection evaluation.

The device has been qualified to meet the JEDEC
standard for Pb-Free assembly. The temperatures
and time intervals listed are based on the Pb-Free
small body requirements. The temperatures refer to
the topside of the package, measured on the
package body surface. The FX-730 device is
hermetically sealed so an aqueous wash is not an
issue.
