AFE1103E/1K 数据手册

In most systems, it will be natural to derive PV_DDfrom the

AV_DDsupply. A 5Ω to 10Ω resistor should be used to

connect PV_DDto the analog supply. This resistor in combi-

nation with the 10µF capacitor form a lowpass filter—

keeping glitches on AV_DDfrom affecting PV_DD. Ideally,

PV_DDwould originate from the analog supply (via the

resistor) near the power connector for the printed circuit

board. Likewise, PGND should connect to a large PCB trace

or small ground plane which returns to the power supply

connector underneath the PV_DDsupply path. The PGND

“ground plane” should also extend underneath PLL_INand

PLL_OUT(pins 47 and 48).

LAYOUT

The analog front end of an HDSL system has a number of

conflicting requirements. It must accept and deliver digital

outputs at fairly high rates of speed, phase-lock to a high-

speed digital clock, and convert the line input to a high-

precision (14-bit) digital output. Thus, there are really three

sections of the AFE1103: the digital section, the phase-

locked loop, and the analog section.

The power supply for the digital section of the AFE1103 can

range from 3.3V to 5V. This supply should be decoupled to

digital ground with a ceramic 0.1µF capacitor placed as

close to DGND (pin 12) and DV_DD(pin 13) as possible.

Ideally, both a digital power supply plane and a digital

ground plane should run up to and underneath the digital

pins of the AFE11103 (pins 3 through 26). However, DV_DD

may be supplied by a wide printed circuit board (PCB) trace.

A digital ground plane underneath all digital pins is strongly

recommended.

The remaining portion of the AFE1103 should be considered

analog. All AGND pins should be connected directly to a

common analog ground plane and all AV_DDpins should be

connected to an analog 5V power plane. Both of these planes

should have a low impedance path to the power supply.

Ideally, all ground planes and traces and all power planes

and traces should return to the power supply connector

before being connected together (if necessary). Each ground

and power pair should be routed over each other, should not

overlap any portion of another pair, and the pairs should be

separated by a distance of at least 0.25 inch (6mm). One

exception is that the digital and analog ground planes should

be connected together underneath the AFE1103 by a small

trace.

The phase-locked loop is powered from PV_DD(pin 2) and its

ground is referenced to PGND (pin 1). Note that PV_DDmust

be in the 4.75V to 5.25V range. This portion of the AFE1103

should be decoupled with both a 10µF Tantalum capacitor

and a 0.1µF ceramic capacitor. The ceramic capacitor should

be placed as close to the AFE1103 as possible. The place-

ment of the Tantalum capacitor is not as critical, but should

be close. In each case, the capacitor should be connected

between PV_DDand PGND.
