TDA18260HN Datasheet Dual Cable Silicon Tuner

Manufacturer: NXP Semiconductors

Overview: TDA18260HN Dual cable Silicon Tuner Rev. 2 — 14 December 2010 Preliminary data sheet 1.

General Description

The TDA18260HN is a dual Silicon Tuner IC designed specifically for high definition multi-tuner cable Set Top Boxes (STBs) supporting single streaming and multi-streaming PVR STBs with watch, record, video-on-demand and in-home video distribution capability.

Used in conjunction with the TDA10025HN (dual digital channel demodulator), the TDA18260HN covers all worldwide digital cable standards.

• The TDA18260HN ensures a low system cost as: – Costly ponents such as low noise amplifiers, Surface Acoustic Wave (SAW) filters and incremental crystal oscillators have been eliminated from the system Bill Of Materials (BOM) • The TDA18260HN high performance Silicon Tuner meets today’s digital cable TV reception needs with: – Matched performance levels for master and slave tuners – Low power consumption – High linearity – Low noise figure • The TDA18260HN ensures ease of use with: – Easy on-board integration – Efficient and effective PCB design – Reduced external ponents 2.

Key Features

  • Supports up to three tuner functions (up to six individual streams) specifically aimed for gateways and STBs:.
  • Two low IF outputs.
  • Two RF outputs to drive slave tuners.
  • Integrated splitter eases and simplifies the design of dual Tuner PVR.
  • Integrated wideband gain control.
  • Extended frequency coverage up to 1002 MHz.
  • Single 3.3 V power supply.
  • Low power consumption.
  • Multistandard cable receptions.
  • Enhanced Band-pass filter to reduce in band third.
