DESCRIPTION
The PCK2111 is a low skew programmable 1:10 LVDS clock
distribution device. The selected input signal is fanned out to 10
identical differential outputs.
The PCK2111 features an 11-bit Shift Register with a serial-in and a
Control Register. The purpose of the Control Register is to enable or
power off each output clock channel and to select the clock input.
The PCK2111 is specifically designed, modeled and produced with
low skew as the key goal. Optimal design and layout serve to
minimize gate-to-gate skew within a device. The final result is a
dependable guaranteed low skew device.
The PCK2111 can be used for high performance clock distribution in
+2.5 V systems with LVDS levels. Designers can take advantage of
the device’s performance to distribute low skew clocks across the
backplane or the board.
