The reset default divide ratio for RCLK is 64:1 with SCLK held at logic 0 and VCLK held at logic 1. When
choosing certain video timing parameters, exercise caution if the selected RCLK frequency is less than the
selected VCLK frequency. Refer to Appendix B for a more detailed discussion.

(dot clock/4 as an example)
RCLK = SCLK

The input-clock-selection register is used to select the desired input clock source. Table 2–4 details how to
program the various options.

Select CLK4 as TTL clock source
Select CLK3/CLK4 as ECL clock source up to 140 MHz
Select CLK1/CLK2 as ECL clock source up to device limit
10
Select CLK0 as doubled TTL clock source
11
Select CLK1 as doubled TTL clock source
12
Select CLK2 as doubled TTL clock source

CLK0 is chosen at reset as required for VGA pass-through.
NOTES:
1. Register bits 3 and 7 are don’t-care bits.
2. Register bits 5 and 6 are reserved.
3. When the clocks are selected from one input clock source to another, a minimum of 30 ns is needed
before the new clocks are stabilized and running.
