21-Bit Deserializers with Programmable

Spread Spectrum and DC Balance

General Description

Features

♦ Programmable ±±4% ±ꢀ4% or ꢁꢂꢂ FꢃreaꢄꢅFꢃepꢆrtm

The MAX9242/MAX9244/MAX9246/MAX9254 deserialize

three LVDS serial-data inputs into 21 single-ended LVC-

MOS/ LVTTL outputs. A separate parallel-rate LVDS clock

provides the timing for deserialization. The MAX9242/

MAX9244/MAX9246/MAX9254 feature spread-spectrum

capability, allowing the output data and clock frequency

to spread over a specified range to reduce EMI. The sin-

gle-ended data and clock outputs are programmable for

a frequency spread of 2ꢀ, 4ꢀ, or no spread. The

spread-spectrum function is also available when the

MAX9242/MAX9244/MAX9246/MAX9254 operate in non-

DC-balanced mode. The modulation rate of the spread is

32kHz for a 33MHz LVDS clock input and scales linearly

with frequency. The single-ended outputs have a sepa-

rate supply, allowing +1.8V to +5V output logic levels.

The MAX9254 features high output drive current for both

data and clock outputs for faster transition times in the

presence of heavy capacitive loads.

The MAX9242/MAX9244/MAX9246/MAX9254 feature pro-

gram-mable DC balance, allowing isolation between a

serializer and deserializer using AC-coupling. The

MAX9242/MAX9244/MAX9246/MAX9254 operate with the

MAX9209/MAX9213 serializers and are available with a

rising-edge strobe (MAX9242) or falling-edge strobe

(MAX9244/MAX9246/MAX9254). The LVDS inputs meet

ISO 10605 ESD specifications with 30kV Air-ꢁap

Discharge and 6kV Contact Discharge ratings.
