Product Description
PI6CV855 PLL clock device is developed for SSTL_DDR SDRAM
applications. This PLL Clock Buffer is designed for 2.5 V
DDQ
and
2.5V AV
DD
operation and differential data input and output levels.
The device is a zero delay buffer that distributes a differential clock
input pair (CLK, CLK) to five differential pairs of clock outputs
(Y[0:4], Y[0:4]) and one differential pair feedback clock outputs
(FBOUT, FBOUT). The clock outputs are controlled by the input
clocks (CLK, CLK), the feedback clocks (FBIN,FBIN), and the
Analog Power input (AV
DD
). When the AV
DD
is strapped low, the
PLL is turned off and bypassed for test purposes.
When the input frequency falls below a suggested detection fre-
quency that is below the operating frequency of the PLL, the device
will enter a low power mode. In low power mode, PLL is turned OFF,
Y[0:4] and Y[0:4] outputs are 3-stated.
The PI6CV855 is able to track Spread Spectrum Clocking to reduce
EMI.
Product Features
PLL clock distribution optimized for SSTL_2 DDR SDRAM
applications.
Distributes one differential clock input pair to five differential
clock output pairs.
Inputs (CLK,CLK) and (FBIN,FBIN): SSTL_2
Outputs (Yx, Yx), (FBOUT, FBOUT): SSTL_2
External feedback pins (FBIN,FBIN) are used to
synchronize the outputs to the clock input.
Operates at AV
DD
= 2.5V for core circuit and internal PLL,
and V
DDQ
= 2.5V for differential output drivers
Available Package:
Plastic 28-pin TSSOP
