IT6692FN
General Description
The IT6692FN is a high-performance single-chip HDMI to VGA converter. Combined with HDMI 1.3
receiver and triple DACs, the IT6692FN supports HDMI input and VGA output by conversion function.
The build-in HDMI receiver is fully compliant with HDMI 1.3a specification. With HDMI 1.3a receiver,
the IT6692FN can support resolutions up to Full HD ( 1080P ), WUXGA and UXGA. Also the build-in
triple DACs can support up to 10 bit deep colors.
The single chip IT6692FN provides high performance, cost effective, HDMI2VGA conversion function,
and it can help modern NBs like ultrabooks and tablets to be compatible with traditional VGA only
projectors, monitors, and TVs.
With Embedded MCU and Flash, IT6692FN is easy to program thru the ISP interface. Customers
need no external Flash and MCU to save the BOM cost and board size.
Features ( HDMI 1.3 RX )
• Single-link HDMI 1.3 receiver
• Compliant with HDMI 1.3a and DVI 1.0 specifications
• Supporting link speeds of up to 2.25Gbps (link clock rate of 225MHz).
• Auto-calibrated input termination impedance provides process-, voltage- and
temperature-invariant matching to the input transmission lines.
Features ( VGA DACs)
• Tripe 10-Bit DAC Converters
• 200 MSPS Throughput Rate
• Complementary Outputs
• DAC Output Current Range 2mA to 18.5mA

Notes:
1. Typ: OVDD=AVCC33 =3.3V, IVDD=AVCC18=PVCC18=APVCC18=VDDA=VDDC=1.8V, Typical pattern
Max: OVDD=AVCC33 =3.3V, IVDD=AVCC18=PVCC18=APVCC18=VDDA=VDDC=1.8V, Worst case pattern
2. PCLK=27MHz: 480p without Audio
PCLK=74.25MHz: 1080i without audio,
PCLK=148.5MHz: 1080p without audio,
PCLK=222.75MHz: 1080p@36-bit Deep Color without audio
3. PWTOTAL_OP are calculated by multiplying the supply currents with their corresponding supply voltage and summing up all the items.
