Q6214TT15D-ISDBT

Q6214TT15D-ISDBT

Based on the naming convention and suffix-ISDBT, Q6214TT15D-ISDBT is almost certainly adigital TV demodulator Integrated Circuit (IC) designed specifically for theISDB-T broadcast standard. 這是一個細分:

1. Manufacturer: This part number follows the naming scheme of NXP Semiconductors (formerly Philips Semiconductors).
2. 功能: It’s a demodulator IC for terrestrial digital TV.
3. 標準:ISDB-T (綜合業務數位廣播 – 陸地的). This is the digital TV standard used primarily in:
   • 日本
   • 巴西
   • Most of South America
   • The Philippines
4. 主要特點 (Typical for this family):
   • Full Compliance: Supports all ISDB-T transmission modes (1-3, 13-部分, 1-部分).
   • 頻率範圍: Typically covers VHF Band III (170-230 兆赫茲) and UHF Bands IV/V (470-862 兆赫茲).
   • 輸入: Takes an 如果 (Intermediate Frequency) input signal from an analog TV tuner module.
   • 輸出: Provides a demodulated and error-corrected MPEG-2 傳輸流 (TS) output via a standard interface like Serial or Parallel.
   • 介面: Usually includes an I²C interface for control and configuration by the host system (例如, the main processor in the TV or set-top box).
   • 一體化: May include features like RF AGC (Automatic Gain Control) output to control the preceding tuner, and a built-in ADC (Analog-to-Digital Converter).
   • 低功耗: Designed for consumer electronics applications.
   • 包裹: Likely a surface-mount package like TSSOP.
5. 典型應用: This chip is a core component found inside:
   • ISDB-T Digital TVs
   • ISDB-T Set-Top Boxes (STBs)
   • ISDB-T PC TV Tuner Cards/Sticks
   • Other devices receiving free-to-air digital terrestrial TV broadcasts in ISDB-T regions.

Important Note on Availability:

• The Q6214TT15D is part of an older generation of NXP demodulators.
• While it might still be available from distributors or in existing designs, NXP has likely transitioned to newer, more integrated, or multi-standard demodulator families (like the TDA series or more recent SoCs).
• If you are sourcing this part, check its current availability and lifecycle status (例如, Active, Not Recommended for New Designs (NRND), or Obsolete) with authorized distributors like Digi-Key, 貿澤, or directly with NXP.

In Summary:

這Q6214TT15D-ISDBT is anNXP Semiconductors demodulator IC specifically engineered to receive and decode digital television signals broadcast using theISDB-T標準. It’s a key component in TVs, 機上盒, and tuners used in Japan, 巴西, 南美洲, and the Philippines.
