STMicroelectronics 

ADE3800

8 ADE3800 vs ADE3700

ADE3800 vs ADE3700

The following gives an overview of the main differences between ADE3700 and ADE3800:

Package

● 100 pin LQFP for LVDS 1&2 channels and RSDS 1 channel application

● 128 pin LQFP for RSDS 2 pixel per clock support

● 5V tolerant inputs do not have internal pull-up resistors

I2C Interface

● Add Block Transfer for fast internal data move/swap/copy

Registers

● Now all registers runs on XCLK

● RGB register address ordering is reversed to BGR

Analog Front End (ADC & SOG)

● New ADC design with higher performances

● Add Internal SOG Sync Stripper with bypass option (external SOG TTL pin)

● SOG activity can operate while ADC Power is down (wakeup from DPMS by SOG support)

● Per channel skew control

● Analog Filter bandwidth programmable

● Gain and Offset independent and linear

● 10-bit ADC using Analog Dithering Technique (ADTH)

Line Lock PLL (LLK)

● Synthesized Internal HSync has 50% duty cycle

● Phase step is 4 times more precise

● Phase range can exceed one clock period delay

● Lock filter removed

● Fewer registers, simplifies some programming

● Clock and Phase are both shadowed

● FM Modulation amplitude step is 16 times more precise

Sync Measurement (SMEAS)

● Remove out of range register

● Add Fast Mute function

● Group all the fast mute flags in SMEAS with sticky bit and enable
