System Description

1. CCD

The following lists the pixels of the CCD sensors that can be used with the HD49815TF. For other

pixel numbers, contact our sales dept.

512 (H) × 492 (V) NTSC

512 (H) × 582 (V) PAL

682 (H) × 492 (V) NTSC

681 (H) × 582 (V) PAL

2. CDS/AGC + 10-bit ADC

The HD49323AF-01 (manufactured by Hitachi) is recommended as an optimal CDS/AGC + 10-bit

ADC IC for the HD49815TF. Since the HD49323AF-01 provides a correlated double sampling circuit

that realizes high S/N and an automatic gain control (AGC) circuit that implements programmable

control of 0 dB to 34.7 dB, it enables a high-image-quality camera system when used in conjunction

with the HD49815TF.
