This part consists of a triple 6th order filter with selectable 30MHz or 8MHz frequencies. A 2-to-1 multiplexer is provided on each filter channel. The triple filters are intended for either YUV or RGB signals. All channels accept DC coupled ground-referenced 1V signals. The filters provide 2Vpp signals into AC coupled terminated loads. The low-pass filters are powered by 3.3V and the outputs by 5.0V. Applications • Cable Set top boxes • Satellite Set top boxes • DVD players • HDTV • Personal Video Recorders (PVR) • Video On Demand (VOD) Functional Block Diagram INMUX (A/B) Filter Select (HD/SD) RINA (VINA) 6dB ROUT (VOUT) RINB (VINB) GINA (YINA) 6dB GOUT (YOUT) GINB (YINB) BINA (UINA) 6dB BOUT (UOUT) BINB (UINB) YIN 6dB YOUT AUXIN CVOUT CIN 0.5V (Internal Reference) CVMUX (YIN/CIN; AUXIN) 6dB COUT REV. 4C June 28, 2004 DATA SHEET FMS6419 Electrical Specifications (TC = 25°C, Vi = 1Vpp; VCCA = 3.3V, VCCO = 5.0V, all inputs AC coupled with 0.1µF, all outputs AC coupled with 220µF into 150Ω, referenced to 400kHz; unless otherwise noted) Symbol ICCA ICCO Vi Vil Vih PSSR Parameter Supply Supply Current1 Current1 Low1 High1 Conditions VCCA no load VCCO no load Reference to ground FSEL, INMUX, CVMUX FSEL, INMUX, CVMUX DC 0 2.4 -40 Min 50 50 Typ 85 85 1.3 0.8 VCCO Max Units 120 120 mA mA V V V dB Input Voltage Max Digital Input Digital Input PSSR (all channels) Standard Definition Electrical Specifications (TC = 25°C, Vi = 1Vpp; VCCA = 3.3V, VCCO = 5.0V, FSEL = 0, all inputs AC coupled with 0.1µF, all outputs AC coupled with 220µF into 150Ω,referenced to 400kHz; unless otherwise noted) Symbol AVRGBSD AVYC AVCV f1dBSD fCSD fSBSD fSBCV dG dφ INMUXISO SNR Parameter RGB SD Gain YC Gain CV Gain 1 1 1 1 Conditions R,G,B channels SD Mode Y, C channels CV channel R,G,B,Y,C,CV channels R,G,B,Y,C,CV channels 1 Min 5.4 5.4 5.4 4 -37 -37 Typ 6.0 6.0 6.0 6.0 8.2 -55 -55 0.6 0.2 -60 -70 70 Max Units 6.6 6.6 6.6 dB dB dB MHz MHz dB dB % ° dB dB dB -1dB Bandwidth for SD -3dB Bandwidth for SD Attenuation: SD (stopband reject) Differential Gain Differential Phase INMUX Isolation Signal-to-Noise Ratio R,G,B,Y,C channels at f = 27MHz CV channel at f = 27MHz R,G,B,Y,C,CV channels R,G,B,Y,C,CV channels at 1MHz at 1MHz R,G,B,Y,C,CV channels, NTC-7 weighting 4.2MHz lowpass, 100kHz highpass Delay from input to output at 4.5MHz f = 3.58MHz (referenced to 400kHz) f = 3.58MHz (referenced to 400kHz) Attenuation: SD (stopband reject)1 XTALKYCRGB Crosstalk (channel-to-channel) tpdSD tCLDCV tCLGCV Prop Delay for SD Chroma-Luma Delay CVOUT1 Chroma-Luma Gain CVOUT 1 80 -35 98 2 102 35 106 ns ns % Notes: 1. 100% tested at 25°C.
