Not Recommended for New Designs VS P2 VSP2582 582 www.ti.com SBES002B – JUNE 2008 – REVISED JUNE 2011 CCD ANALOG FRONT-END FOR DIGITAL CAMERAS
Check for Samples: VSP2582 FEATURES DESCRIPTION The VSP2582 is a complete mixed-signal processing
IC for digital cameras that provides correlated double
sampling (CDS) and analog-to-digital conversion
(ADC) for the output of charge-coupled device (CCD)
array. The CDS extracts video information of the
pixels from the CCD signal, and the ADC converts it
to a digital signal. For varying illumination conditions,
–9 dB to +35 dB very stable gain control is provided.
This gain control is linear in dB. Input signal clamping
and offset correction of the input CDS are also
provided. 1 2 CCD Signal Processing:
– 36-MHz Correlated Double Sampling (CDS)
12-Bit Analog-to-Digital Conversion:
– 36-MHz Conversion Rate
– No Missing Codes Ensured
78-dB Input-referred SNR (at CDS Gain 0 dB)
Programmable Black Level Clamping
Programmable Gain Amp (PGA):
–9 dB to +35 dB, –3 dB to +9 dB
by Analog Front Gain (CDS)
–6 dB to +26 dB by Digital Gain
Portable Operation: …
