Description
Output Enable. Tri-states all output clocks when low. All running when high (VDDIO).
Crystal connection. Connect to a 27 MHz fundamental parallel mode crystal.
Crystal connection. Connect to a 27 MHz fundamental parallel mode crystal, or clock
Connect to +5V.
Connect to ground.
Input select. Determines DCLK and DCLK/2 per table above. Must be ≤ VDDIO.
Buffered crystal oscillator 27 MHz clock output. Amplitude = VDDIO.
NTSC or PAL 4X subcarrier frequency per table above. Amplitude = VDDIO.
48.00 MHz clock output for Intel graphics processor. Amplitude = VDDIO.
NTSC or PAL 8X subcarrier frequency per table above. Amplitude = VDDIO.
Audio clock, or Square Pixel clock, per table above. Amplitude = VDDIO.
Connect to ground.
Connect to +5V or +3.3V. Amplitude of output clocks will match this voltage.
Buffered crystal oscillator divided by two 13.5 MHz clock output. Amplitude = VDDIO.
Input select 0 for ACLK. Determines ACLK frequency per table above. Must be ≤ VDDIO.
Input select 1 for ACLK. Determines ACLK frequency per table above. Must be ≤ VDDIO.
Key: I = Input; O = output; P = power supply connection; XI, XO = crystal connections.
