The AD9253-EP is available in a RoHS-compliant, 48-lead LFCSP  
and is specified over an extended temperature range of −55°C to  
+125°C. This product is protected by a U.S. patent. Additional  
application and technical information can be found in the AD9253  
data sheet.  
GENERAL DESCRIPTION  
The AD9253-EP is a quad, 14-bit, 125 MSPS analog-to-digital  
converter (ADC) with an on-chip, sample-and-hold circuit  
designed for low cost, low power, small size, and ease of use.  
The product operates at a conversion rate of up to 125 MSPS  
and is optimized for outstanding dynamic performance and  
low power in applications where a small package size is critical.  
PRODUCT HIGHLIGHTS  
1. Small Footprint. Four ADCs are contained in a small, space-  
saving package.  
2. Low power of 110 mW/channel at 125 MSPS with scalable  
power options.  
3. Ease of Use. A DCO operates at frequencies of up to 500 MHz  
and supports double data rate (DDR) operation.  
4. User Flexibility. The SPI control offers a wide range of  
flexible features to meet specific system requirements.  
The ADC requires a single 1.8 V power supply and LVPECL-/  
CMOS-/LVDS-compatible sample rate clock for full performance  
operation. No external reference or driver components are required  
for many applications.  
The ADC automatically multiplies the sample rate clock for the  
appropriate LVDS serial data rate. A data clock output (DCO) for  
capturing data on the output and a frame clock output (FCO)  
for signaling a new output byte are provided. Individual channel  
power-down is supported and typically consumes less than 2 mW  
when all channels are disabled. The ADC contains several features

2 Crosstalk is measured at 70 MHz with an −1.0 dBFS analog input on one channel and no input on the adjacent channel.  
3 The overrange condition is specified with 3 dB of the full-scale input range.  
4 PSRR is measured by injecting a sinusoidal signal at 10 MHz to the power supply pin and measuring the output spur on the FFT. PSRR is calculated as the ratio of the  
amplitudes of the spur voltage over the pin voltage, expressed in decibels.
