ISDB modulator

Outline

NDS2405C ISDB-T modulator is developed to adapt Japan, Brazil, Argentina and other South American country’s terrestrial digital television. The modulator's channel encoding and modulation mode is fully complying with the ARIB STD-B31 standard. This ISDB-T modulator supports four ASI hot backup input, single frequency network, and multi-frequency network. In order to improve the output performance of the transmitter, this ISDB-T modulator also simultaneously supports adaptive linear and nonlinear digital pre-distortion, layered transmission and three transmission modes. Furthermore, this device can be upgraded and controlled through network system, which can be widely used in ISDB-T digital broadcasting network's setting up and set-top box design's production and test.

 

Features

1.Fully complying with ISDB-T (ARIB STD-B31) and ISDB-TB standard

2.4 ASI in, 1 RF in, 10MHz reference clock and 1PPS in

3.Layered transmission with A, A+B, A+B+C hierarchy modes

4.ISDB-T BTS input (with IIP packet), support single frequency and multi-frequency network

5.Three transmission modes: mode1(2k), mode2(4k), mode3(8k)

6.Supports adaptive linear digital pre-distortion (DPD)

7.Supports adaptive non-linear digital pre-distortion (DPD )

8.MER42db

9.RF output range: 30~960MHz with 1Hz step

10.Constant temperature crystal oscillating and excellent frequency stability (reach up to 0.1ppm)

11.LCD display, keyboard and SNMP software operation
