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
