Hot-Swappable, 21-Bit, DC-Balanced LVDS

Deserializers

General Description

Features

The MAX9234/MAX9236/MAX9238 deserialize three

LVDS serial-data inputs into 21 single-ended

LVCMOS/LVTTL outputs. A parallel-rate LVDS clock

received with the LVDS data streams provides timing for

deserialization. The outputs have a separate supply,

allowing 1.8V to 5V output logic levels. All these devices

are hot-swappable and allow “on-the-fly” frequency

programming.

♦ DC Balance Allows AC-Coupling for Wider Input

Common-Mode Voltage Range

♦ On-the-Fly Frequency Programming

♦ Operating Frequency Range

8MHz to 34MHz (MAX9234/MAX9236)

16MHz to 66MHz (MAX9238)

♦ Falling-Edge Output Strobe (MAX9236/MAX9238)

The MAX9234/MAX9236/MAX9238 feature DC balance,

which allows isolation between a serializer and deseri-

alizer using AC-coupling. Each deserializer decodes

data transmitted by one of the MAX9209/MAX9211/

MAX9213/MAX9215 serializers.

♦ Slower Output Transitions for Reduced EMI

(MAX9234/MAX9236)

♦ High-Impedance Outputs when PWRDWN Is Low

Allow Output Busing

The MAX9234 has a rising-edge output strobe. The

MAX9236/MAX9238 have a falling-edge output strobe.

The MAX9234/MAX9236/MAX9238 operate in DC-

balanced mode only.

♦ 5V-Tolerant PWRDWN Input

♦ PLL Requires No External Components

♦ Up to 1.386Gbps Throughput

The MAX9234/MAX9236 operate with a parallel input

clock of 8MHz to 34MHz, while the MAX9238 operates

from 16MHz to 66MHz. The transition time of the single-

ended outputs is increased on the low-frequency version

parts (MAX9234/MAX9236) for reduced EMI. The LVDS

inputs meet ISO 10605 ESD specification, 25kV for Air-

Gap Discharge and 8kV Contact Discharge.

♦ Separate Output Supply Pins Allow Interface to

1.8V, 2.5V, 3.3V, and 5V Logic

♦ LVDS Inputs Meet ISO 10605 ESD Requirements

♦ LVDS Inputs Conform to ANSI TIA/EIA-644 LVDS

Standard

The MAX9234/MAX9236/MAX9238 are available in 48-pin

TSSOP packages and operate over the -40°C to +85°C

temperature range.

♦ Low-Profile, 48-Lead TSSOP Package

♦ +3.3V Main Power Supply

♦ -40°C to +85°C Operating Temperature Range
