_______________Detailed Description
Figure 3 is a functional diagram of the MAX3264/
MAX3265/MAX3268/MAX3269/MAX3765/MAX3768 lim-
iting amplifiers. A linear input buffer drives a multistage
limiting amplifier and an RMS power-detection circuit.
Offset correction with lowpass filtering ensures low
deterministic jitter. The output buffer produces a limited
output signal. The MAX3264/MAX3265/MAX3765 pro-
duce a CML output, while the MAX3268/MAX3269/
MAX3768 produce a PECL-compatible output signal.
Schematics of these input/output circuits are shown in
Figures 4 through 7.
RMS Power Detect with
Loss-of-Signal Indicator
An RMS power detector looks at the signal from the
input buffer and compares it to a threshold set by the
TH resistor (see Typical Operating Characteristics for
appropriate resistor values). The signal-detect informa-
tion is provided to the LOS outputs, which are internally
terminated with 8k (MAX3265/MAX3269/MAX3765) or
16k (MAX3264/MAX3268/MAX3768) pullup resistors.
The LOS outputs meet TTL voltage specifications when
loaded with a resistor ≥ 4.7k.
