Product details
Overview
TW6869-TA1-CRH from Intersil (now Renesas) is an 8-channel analog video and audio capture IC for PC-based DVR and video analytics systems. It integrates eight NTSC/PAL/SECAM decoders with 10-bit ADCs, adaptive 4H comb filters, eight audio ADCs (8/16-bit, 8–48kHz sampling), and a PCIe x1 media bridge DMA controller supporting up to 8 real-time D1 video + 8 audio channels.
For engineers reviewing the TW6869-TA1-CRH datasheet, TW6869-TA1-CRH pinout, TW6869-TA1-CRH application, or TW6869-TA1-CRH equivalent, key selection considerations include industrial-temperature operation (−40°C to +85°C), TQFP-144 package compatibility, PCIe 1.1 endpoint compliance, motion detection per channel, and support for UYVY/YUY2/YUV420/RGB565 output formats.
Technical Context
The TW6869-TA1-CRH implements a dedicated PCIe 1.1 endpoint controller with configurable packet sizes (128/256/512 bytes) and a proprietary high-efficiency DMA engine optimized for sustained throughput near PCIe x1 theoretical bandwidth (250 MB/s). Its video processing pipeline includes per-channel sync detection, programmable AGC/clamping, and Y/C separation via adaptive 4H comb filtering for NTSC/PAL or notch/band-pass for SECAM.
Each of the eight video channels features independent cropping (HDELAY/HACTIVE/VDELAY/VACTIVE registers), horizontal scaling (12-bit HSCALE, up to 1/16 ratio), vertical line-dropping scaling (12-bit VSCALE), and hardware motion detection. Audio paths include decimation filtering, sample rate selection (8/16/32/44.1/48 kHz), and white-peak AGC - all fully register-configurable via host software.

FAQ
What video standards does the TW6869-TA1-CRH support with automatic detection?
The TW6869-TA1-CRH supports automatic detection of NTSC (M/N/4.43), PAL (B/D/G/H/I/K/L/M/N/60), and SECAM (M) standards using burst-phase, burst-frequency, and frame-rate analysis. The Standard Selection (SDT) register reports the identified standard, and software can override auto-detection to lock to a specific format. All supported standards are confirmed in the FN7867 Rev. 2.00 datasheet Table 1.
Does the TW6869-TA1-CRH require external anti-aliasing filters on its analog video inputs?
No, the TW6869-TA1-CRH integrates on-die analog anti-aliasing filters and 10-bit ADCs for all eight video channels. As stated on page 10 of the FN7867 datasheet, only AC coupling capacitors and termination resistors are needed externally - eliminating BOM cost and layout complexity associated with discrete filter networks.
How does the TW6869-TA1-CRH handle PCIe bandwidth optimization for multi-channel video?
The TW6869-TA1-CRH uses a proprietary DMA controller that dynamically manages PCIe x1 transaction scheduling, supports configurable packet sizes (128/256/512 bytes), and implements hardware-friendly data flow control to prevent bus contention. This architecture achieves sustained throughput close to the PCIe x1 theoretical limit (250 MB/s), enabling 8 real-time D1 streams without frame loss - as verified in the "DMA Controller" feature section of the datasheet.
What is the function of the internal video and audio generator in the TW6869-TA1-CRH?
As documented on page 20 of the FN7867 datasheet, the internal video and audio generator provides built-in test patterns (e.g., color bars, moving bars) and tone signals - allowing full functional validation of the TW6869-TA1-CRH's signal chain, driver stack, and host application without external video/audio sources. This accelerates development and reduces test setup time.
Is the TW6869-TA1-CRH pin-compatible with other variants in the TW686x family?
Yes, the TW6869-TA1-CRH shares identical pinout and package (TQFP-144) with the base TW6869-TA1-CR variant; the 'H' suffix denotes industrial temperature qualification only. Pin compatibility is confirmed in the "Ordering Information" table (page 7) and "Pin Configuration" diagram (page 6) of FN7867 Rev. 2.00 - enabling drop-in replacement in thermally demanding environments without PCB redesign.
