EEPROM PROGRAMMABLE VCXO CLOCK GENERATOR  
IDT5V19EE903  
Description  
Features  
The IDT5V19EE903 is a programmable clock generator  
intended for high performance data-communications,  
telecommunications, consumer, and networking  
applications. There are four internal PLLs, each individually  
programmable, allowing for four unique non-integer-related  
frequencies. The frequencies are generated from a single  
reference clock. The reference clock can come from one of  
the two redundant clock inputs. Automatic or manual  
switchover function allows any one of the redundant clocks  
to be selected during normal operation.  
Four internal PLLs  
Internal non-volatile EEPROM  
2
Fast (400kHz) mode I C serial interface  
Input frequency range: 1 MHz to 200 MHz  
Output frequency range: 4.9 kHz to 200 MHz  
Reference crystal input with programmable linear load  
capacitance  
– Crystal frequency range: 8 MHz to 50 MHz  
(maximum crystal range is best effort)  
The IDT5V19EE903 is in-system, programmable and can  
2
be programmed through the use of I C interface. An  
Integrated VCXO  
internal EEPROM allows the user to save and restore the  
configuration of the device without having to reprogram it on  
power-up.  
Each PLL has a 7-bit reference divider and a 12-bit  
feedback-divider  
8-bit output-divider blocks  
Each of the four PLLs has an 7-bit reference divider and a  
12-bit feedback divider. This allows the user to generate  
four unique non-integer-related frequencies. The PLL loop  
bandwidth is programmable to allow the user to tailor the  
PLL response to the application. For instance, the user can  
tune the PLL parameters to minimize jitter generation or to  
maximize jitter attenuation. Spread spectrum generation  
and/or fractional divides are allowed on two of the PLLs.  
Fractional division capability on one PLL  
Two of the PLLs support spread spectrum generation  
capability  
I/O Standards:  
– Outputs - 3.3 V LVTTL/ LVCMOS  
– Inputs - 3.3 V LVTTL/ LVCMOS  
Programmable slew rate control  
Programmable loop bandwidth  
Programmable output inversion to reduce bimodal jitter  
There are a total of six 8-bit output dividers. The outputs are  
connected to the PLLs via a switch matrix. The switch  
matrix allows the user to route the PLL outputs to any  
output bank. This feature can be used to simplify and  
optimize the board layout. In addition, each output's slew  
rate and enable/disable function is programmable.  
Redundant clock inputs with auto and manual switchover  
options  
Individual output enable/disable  
Power-down mode  
3.3V core V  
DD  
Available in TSSOP and VFQFPN packages  
-40 to +85 C Industrial Temp operation
