PIN FUNCTIONS

DESCRIPTION

NAME

B9~ B2

ACT1...ACT8

Active termination input pins for CH1~8. 1 µF capacitors are recommended. See the Applicaiton

Information section.

A1, D8, D9,

AVDD

3.3V Analog supply for LNA, VCAT, PGA, LPF and CWD blocks.

E8, E9, K1

AVDD_5V

5.0V Analog supply for LNA, VCAT, PGA, LPF and CWD blocks.

J6, J7, K8, L3,

AVDD_ADC

1.8V Analog power supply for ADC.

M1, M2

C1, D1~D7,

E3~E7, F3~F7,

G1~G7,

AVSS

Analog ground.

H3~H7,J3~J5,

Negative input of differential ADC clock. In the single-end clock mode, it can be tied to GND directly or

CLKM_ADC

through a 0.1µF capacitor.

Positive input of differential ADC clock. In the single-end clock mode, it can be tied to clock signal

CLKP_ADC

directly or through a 0.1µF capacitor.

Negative input of differential CW 16X clock. Tie to GND when the CMOS clock mode is enabled. In the

4X and 8X CW clock modes, this pin becomes the 4X or 8X CLKM input. In the 1X CW clock mode,

CLKM_16X

this pin becomes the quadrature-phase 1X CLKM for the CW mixer. Can be floated if CW mode is not

used.

Positive input of differential CW 16X clock. In 4X and 8X clock modes, this pin becomes the 4X or 8X

CLKP_16X

CLKP input. In the 1X CW clock mode, this pin becomes the quadrature-phase 1X CLKP for the CW

mixer. Can be floated if CW mode is not used.

Negative input of differential CW 1X clock. Tie to GND when the CMOS clock mode is enabled (Refer

CLKM_1X

to Figure 88 for details). In the 1X clock mode, this pin is the In-phase 1X CLKM for the CW mixer.

Can be floated if CW mode is not used.

Positive input of differential CW 1X clock. In the 1X clock mode, this pin is the In-phase 1X CLKP for

CLKP_1X

the CW mixer. Can be floated if CW mode is not used.

Bias voltage and bypass to ground.

≥ 1µF is recommended. To suppress the ultra low frequency noise,

CM_BYP

10 µF can be used.

Negative differential input of the In-phase summing amplifier. External LPF capacitor has to be

CW_IP_AMPINM

connected between CW_IP_AMPINM and CW_IP_OUTP. This pin becomes the CH7 PGA negative

output when PGA test mode is enabled. Can be floated if not used.
