• ^{The VSSD pin must also be connected to these pins.}

VSS

VSSA

Ground for Analog (Pixel PLL Circuitry).

This pin is used to ground the analog portions of the pixel PLL circuitry.

VSSAADC

VSSD

Ground for Analog ADC (Circuitry).

These pins are used to ground the analog portions of the ADC.

Ground for Digital (Pixel PLL and Circuitry for Industry-Standard 2-Wire Serial Interface).

This pin is used to ground the digital portions of the pixel PLL circuitry and the circuitry for an

industry-standard 2-wire serial interface.

VSSDADC

VSSMCLK

VSSPCLK

VSSQ

Ground for Digital ADC (Circuitry).

This pin is used to ground the digital portions of the ADC.

Ground for Memory Clock (Circuitry).

This pin is used to ground the circuitry for the memory clock PPL (that is, MCLK).

Ground for Panel Clock (Circuitry).

This pin is used to ground the circuitry for the panel clock PLL (that is, PNLCLK).

Ground for Output Drivers.

This pin is used to ground output drivers for the pixel PLL circuitry.

VSSQADC

VSSSUB

VSS(TEST)

Ground for Output Drivers for ADC.

These pins are used to ground the pixel data output drivers for the analog-to-digital converter.

Ground for Substrate.

These pins are used to provide ground for the chip substrate.

– Typically, this pin must be connected to ground (the Normal mode).

– When the ICS1531 is in Normal mode, the Calibration registers 38h to 3Ch can be enabled by

using Reg 37:3. (See Section 6.5.39, “Register 37h: PSEL”.)

ICS1531

Normal Mode

In Normal mode, use Reg 37:3 to

enable Calibration Regs 38h to 3Ch.

VSS(TEST)

• ^{Test Mode.}

For the VSS(TEST) pin’s Test-mode function, see Table 3-4.

VSSXTL

Ground for Crystal Oscillator.

This pin is used to ground the internal crystal oscillator circuitry.
