Description
This pin provides the signal ground to the PLL circuit. We
recommend that you separate the analog ground from the digital
ground as shown in 'Figure 3 : S5D2509 Application Circuit' (6p)
for optimum performance (S5D2509's built-in PLL is sensitive to
noise due to wide range PLL characteristics).
This voltage is made in an external loop filter and sent to VCO's
input block. Operation voltage range is about 1  4V, and you
can raise immunity against external noise if you want lower the
VCO sensitivity by allowing the max operation voltage range
possible at 5V power voltage. Refer to 'PLL Control' (30p).
Connect to ground using resistance in order to make the
reference current that need to operate internal PLL (PLL region
control). Refer to 'PLL Control' (30p)'.
PLL gain controlled by controlling VCO Current.
This pin supplies +5V supply voltage to the PLL circuit. We
recommend that you divide the digital and analog power for PLL
as you did in 'Figure 3 : S5D2509 Application Circuit (6p)' to
prevent the influence of clock noise on the
digital block.
Horizontal Flyback : This pin is reference signal source of the
internal PLL.
Serial Data (I²C). We recommend that you use the serial resistor
about 1/ 10 value of 5V pull-up resistor as I²C protocol.
Serial Clock (I²C). We recommend that you use the serial resistor
about 1/ 10 value of 5V pull-up resistor as I²C protocol.
PWM DAC0 Output for DC Control other Peripheral.
PWM DAC1 Output for DC Control other Peripheral.
PWM DAC2 Output for DC Control other Peripheral.
PWM DAC3 Output for DC Control other Peripheral.
PWM DAC4 Output for DC Control other Peripheral.
PWM DAC5 Output for DC Control other Peripheral.
PWM DAC6 Output for DC Control other Peripheral.
PWM DAC7 Output for DC Control other Peripheral.
Vertical Flyback signal : Similar to pin #6, this inputs the negative
polarity vertical flyback signal for syncronizing the vertical control
circuit.
