DESCRIPTION
The CTS100LVEL32 is an integrated ÷2 divider. The reset pin is asynchronous and is asserted on the
rising edge. Upon power-up, the internal flip-flop will attain a random logic state; the reset allows for the
synchronization of multiple CTS100LVEL32’s in a system.
The CTS100LVEL32 is a direct replacement for the On Semiconductor MC100EL/LVEL32.
ENGINEERING NOTES
The CTS100LVEL32 provides a V
BB
output for single-ended use or a DC bias reference for AC coupling to
the device. For single-ended input applications, the V
BB
reference should be connected to one side of the
CLK/CLK¯¯¯¯ differential input pair. The input signal is then fed to the other CLK/CLK¯¯¯¯ input. The V
BB
pin
should be used only as a bias for the CTS100LVEL32 as its sink/source capability is limited. When used,
the V
BB
pin should be bypassed to ground via a 0.01F capacitor.
