21-Bit Deserializers with Programmable

Spread Spectrum and DC Balance

6/MAX9254

General Description

Features

♦ Programmable 4%, 2%, or OFF Spread-Spectrum

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.

Output for Reduced EMI

♦ Programmable DC-Balanced or Non-DC-Balanced

Modes

♦ DC Balance Allows AC-Coupling for Wider Input

Common-Mode Voltage Range

♦ Spread Spectrum Operates in DC-Balanced or

Non-DC-Balanced Mode

♦ High Output Drive (MAX9254)

♦ π / 4 Deskew by Oversampling

(MAX9242/MAX9244/MAX9254)

♦ 16MHz-to-34MHz (DC-Balanced) and 20MHz-to-

40MHz (Non-DC-Balanced) Operation

(MAX9242/MAX9244/MAX9254)

♦ 6MHz-to-18MHz (DC-Balanced) and 8MHz-to-20MHz

The MAX9254 features high output drive current for both

data and clock outputs for faster transition times in the

presence of heavy capacitive loads.

(Non-DC-Balanced) Operation (MAX9246)

♦ Rising-Edge (MAX9242) or Falling-Edge

(MAX9244/MAX9246/MAX9254) Output Strobe

The MAX9242/MAX9244/MAX9246/MAX9254 feature pro-

grammable 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.

♦ High-Impedance Outputs when PWRDWN is Low

Allow Output Busing

♦ Separate Output Supply Allows Interface to +1.8V,

+2.5V, +3.3V, and +5V Logic

♦ LVDS Inputs Meet ISO 10605 ESD Protection at

30kV Air-Gap Discharge and 6kV Contact

Discharge

♦ LVDS Inputs Meet IEC 61000-4-2 Level 4 ESD

Protection at 15kV Air-Gap Discharge and 8kV

Contact Discharge

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

♦ +3.3V Main Power Supply

Automotive Navigation Systems

Automotive DVD Entertainment Systems
