Functional Overview
The SFP-ANA-IO is a Small Form Factor Pluggable (SFP) module with coaxial interface. The HD-BNC
connectors are used to interface the module with 75  coaxial cables.
Receive Channel
The Receive (Rx) channel converts a NTSC/PAL video composite input signal to SD-SDI. The video decoder has a
10bit analog-to-digital video converter (ADC) sampling at 54MHz. With 4x oversampling, it features a DC restore
circuit with offset correction and automatic gain control (AGC) to accurately optimize the full-scale range of the
ADC. The input also has a multi-line adaptive (5-lines) comb filter to minimize the cross-chrominance and
cross-luminance artifacts.
Transmit Channel
The Transmit (TX) channel converts an SD-SDI digital video signal to NTSC/PAL video composite output. The
transmit path of the module has a De-serializer and a composite video encoder with a high speed 10bits
Digital-to-Analog video converter (DAC) that can oversample up to 216MHz.
Module Installation
The module is simply inserted, small end first, under manual pressure. Controlled hot plugging is ensured by
design. The module housing makes initial contact with the router board EMI shield, mitigating potential damage
due to Electrostatic Discharge (ESD).
Technical Specifications
Note that specifications are subject to change without notice.
Absolute Maximum Ratings
Exceeding any of these ratings may permanently damage the module. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
