3-Channel High-Performance TCXO/LVCMOS
Clock Buffer Family
5PB12xx
DATASHEET
Description
The 5PB12xx is a high-performance TCXO/LVCMOS clock
fanout buffer family with individual OE pin for each output.
The CLKIN pin can accept either a square wave (LVCMOS)
or clipped sine wave (such as TCXO clipped sine wave
output) as input.
There are 3 different fan-out versions available: 1:3, 1:4 and
1:6.
The 5PB12xx has industry-leading low jitter and extremely
low current consumption, making it ideal for smart mobile
devices.

External Components
A minimum number of external components are required for proper operation. A decoupling capacitor of 0.01µF should be
connected between VDD on pin 1 and GND on pin 4, as close to the device as possible. A 33
series terminating resistor may
be used on each clock output if the trace is longer than 1 inch.
To achieve the low output skew that the 5PB12xx is capable of, careful attention must be paid to board layout. Essentially, all
four outputs must have identical terminations, identical loads and identical trace geometries. If they do not, the output skew will
be degraded. For example, using a 30
series termination on one output (with 33
on the others) will cause at least 15ps of
skew.
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the 5PB12xx. These ratings, which are standard values
for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions
above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating
conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended
operating temperature range.
