Q6214TT15D-ISDBT

Q6214TT15D-ISDBT

Based on the naming convention and suffix -ISDBT, Q6214TT15D-ISDBT is almost certainly a digital TV demodulator Integrated Circuit (IC) designed specifically for the ISDB-T broadcast standard. Here’s a breakdown:

1. Manufacturer: This part number follows the naming scheme of NXP Semiconductors (formerly Philips Semiconductors).
2. Function: It’s a demodulator IC for terrestrial digital TV.
3. Standard:ISDB-T (Integrated Services Digital Broadcasting – Terrestrial). This is the digital TV standard used primarily in:
   • Japan
   • Brazil
   • Most of South America
   • The Philippines
4. Key Features (Typical for this family):
   • Full Compliance: Supports all ISDB-T transmission modes (1-3, 13-segment, 1-segment).
   • Frequency Range: Typically covers VHF Band III (170-230 MHz) and UHF Bands IV/V (470-862 MHz).
   • Input: Takes an IF (Intermediate Frequency) input signal from an analog TV tuner module.
   • Output: Provides a demodulated and error-corrected MPEG-2 Transport Stream (TS) output via a standard interface like Serial or Parallel.
   • Interfaces: Usually includes an I²C interface for control and configuration by the host system (e.g., the main processor in the TV or set-top box).
   • Integration: May include features like RF AGC (Automatic Gain Control) output to control the preceding tuner, and a built-in ADC (Analog-to-Digital Converter).
   • Low Power Consumption: Designed for consumer electronics applications.
   • Package: Likely a surface-mount package like TSSOP.
5. Typical Application: 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 (e.g., Active, Not Recommended for New Designs (NRND), or Obsolete) with authorized distributors like Digi-Key, Mouser, or directly with NXP.

In Summary:

The Q6214TT15D-ISDBT is an NXP Semiconductors demodulator IC specifically engineered to receive and decode digital television signals broadcast using the ISDB-T standard. It’s a key component in TVs, set-top boxes, and tuners used in Japan, Brazil, South America, and the Philippines.
