Datasheet

When LE is high (> VIH), the CLK input is disabled. IDT recommends keeping LE high to reduce F1130

sensitivity to CLK bus noise when SPI is not being programmed. When LE is low (< VIL), the DATA word can

be programmed into the shift registers. The programmed word is then latched into F1130 on the LE rising

edge (refer to Figure 1). End of data occurs after 14

After power on, the default setting for the VGA is Bypass OFF mode with attenuation set to 30 dB. This means the

amplifier is in the signal path with maximum attenuation.
