Layout Techniques

_________________Circuit Description

The MAX3750/MAX3751 are high-frequency products.

The performance of the circuit is largely dependent

upon layout of the circuit board. Use a multilayer circuit

A simplified block diagram of the single port bypass is

shown in Figure 1. IN+ and IN- drive an input buffer

(INBUFF) with 150Ω of internal differential input termi-

nation. INBUFF drives an output buffer (LOBUFF) and

an input to a multiplexer (MUX).

board with dedicated ground and V

planes. Power

supplies should be capacitively bypassed to the

ground plane with surface-mount capacitors placed

near the power-supply pins.

A low TTL input at SEL selects the signal path of

INBUFF through MUX to the output buffer (OUTBUFF).

When SEL has a high TTL logic level present the signal

path is into LIBUFF, through MUX, to OUTBUFF.

Low-Frequency Cutoff

The low-frequency cutoff is determined by the input

resistance and the coupling capacitor as illustrated by

the following equation:

f = 1 / (2πRC)

In a typical system where R = 150Ω and C = 100nF,

resulting in f = 10kHz.
