CMOS
20 MHz DDS clock input.
20 MHz CMOS clock input to DDS. This
pin may also be used along with CLK OUT for directly connecting
crystals.
Inverted clock output.
Inverted DDS clock output. This pin may also
be used along with CLK IN for directly connecting a crystal.
2x Pixel clock output.
2x oversampled line-locked clock output.
Pixel clock output.
Delayed pixel clock output. LDV runs at 1/2 the
rate of PXCK and its rising edge is useful for transferring CVBS
digital video from the TMC22071A to the TMC22x9x Digital Video
Encoders.
External PXCK input.
Input for external PXCK clock source.
PXCK source select.
Select input for internal or external PXCK.
When HIGH, the internally generated line-locked PXCK is selected.
When LOW, the external PXCK source is enabled.
