PINNING

SYMBOL

PIN

TYPE

DESCRIPTION

XIN

1

I

crystal oscillator input and output pins; in a typical application, a

fundamental oscillator crystal is connected between pins XIN and

XOUT; see note 1

XOUT

2

I

VDDI

3

supply

digital core supply voltage (typically 1.8 V)

PLLVCC

4

supply

analog supply voltage for the PLL (typically 3.3 V)

PLLGND

5

ground

analog ground for the PLL

DGND

6

ground

digital PLL core ground voltage; see note 2

DVCC

7

supply

digital PLL core supply voltage (typically 1.8 V)

VDDI

8

supply

digital ADC supply voltage (typically 1.8 V)

VSSI

9

ground

digital ADC ground voltage; see note 2

VDD3

10

supply

analog ADC supply voltage (typically 3.3 V)

AVS

11

ground

analog ground voltage

VIN2

12

I

analog signal input for channel Q; see note 1

VREFN

13

O

negative analog voltage reference output (typically 1.25 V); a

decoupling capacitor (typically 0.1

µF) must be placed as close as

possible between VREFN and GND

VREFP

14

O

positive analog voltage reference output (typically 2 V); a decoupling

capacitor (typically 0.1

µF) must be placed as closed as possible

between VREFP and GND

VIN1

15

I

analog signal input for channel I; see note 1

AVD

16

supply

analog supply voltage (typically 3.3 V); a 0.1

µF decoupling capacitor

must be placed between AVD and AVS

SADDR0

17

I

TDA10085; other bits of the address are set internally to 000111,

0, 0, 0, 1, 1, 1 plus the SADDR0 bit; see note 1

TMD

18

I

test input; must be connected to ground for normal operation; see

note 1

ENSERI

19

I

enable serial interface input; when HIGH, the serial transport stream

is present on the boundary scan pins (TRST, TDO, TCK, TDI

and TMS); when LOW, the boundary scan pins are available; note 1

IICDIV

20

I

IICDIV = 0 and XIN/4 if IICDIV = 1; see note 1

CTRL1

21

OD

control line output 1; this pin function is directly programmable

output requiring an external pull-up resistor to 3.3 V or to 5 V

CTRL2

22

OD

control line output 2; this pin function is directly programmable

output requiring an external pull-up resistor to 3.3 V or to 5 V

VSSE

23

ground

digital ground voltage; see note 2

VDDE5

24

supply

digital 5 V supply voltage; required for the 5 V tolerance of inputs

VSSI

25

ground

digital core ground voltage; see note 2
