M I C R O T U N E™ 4706 PH5 RF TUNER MODULE (3X8264, 3X8287, 3X8320) ADVANCE DATA SHEET CABLE MODEM APPLICATIONS 1 APPLICATIONS The 4706 PH5 RF Tuner Module is designed for subscriber-side cable modem applications. 2 FEATURES • • • EuroDOCSIS compatible VHF Low, VHF High, and UHF Single 5V power supply • • • • • • All functions controlled by I2C bus Downstream frequency range from 80 MHz to 862 MHz Upstream frequency range from 5 MHz to 65 MHz Antenna input: IEC connector (3x8264) or F-connector (3x8287, 3x8320) Optional horizontal or vertical (3x8320) positioning Additional ESD protection provided (3x8320) 3 INTRODUCTION The 4706 PH5 RF Tuner Module covers a frequency range from 80 MHz to 862 MHz with a channel bandwidth of 8 MHz for downstream signals, and 5 MHz to 65 MHz for upstream signals. Figure 1 4706 PH5 RF Tuner Module The receiver uses a single-conversion approach with the reception frequency range divided into VHF low, VHF high, and UHF. 3X 8264 ED Revision: 02 September 01 Page 1 of 15 8264ED02.doc 4706 PH5 TUNER MODULE (3X 8264, 3X 8287, 3X 8320) ADVANCE DATA SHEET CABLE MODEM APPLICATIONS Band selection and tuning is done via the I2C -bus. A balanced intermediate frequency (IF) output is available with a center frequency of 36.125 MHz. The IF outputs are designed to interface directly with a standard surface acoustical wave (SAW) filter. An automatic gain control (AGC) input allows for external control of the output signal amplitude. The common antenna input/output is realized by an IEC connector or by an Fconnector (75Ω). A digital automatic frequency control (AFC) function can also be realized — the AFC voltage generated by the IF demodulator is fed to a built-in analog/digital converter available via pin 6 and readable via the I²C bus. A DC/DC converter for 33V generation is built in, so that only a single supply voltage of 5V is required. 4 MECHANICAL SPECIFICATIONS This section contains mechanical specifications for the 4706 PH5 RF Tuner Modules. 4.1 MECHANICAL DRAWINGS PIN 1 CONNECTION Reverse channel in 2 3 65,94 14.0 4 Supply voltage VS1 for Power Supply 5 AGC voltage 6 Switch port P6 output/input for ADC 7 NC 8 Supply voltage VS1 for tuner +5V 9 IIC bus signal SCL 10 IIC bus signal SDA 11 Address selection for IIC bus 12 IF output 13 1 2 3 4 5 6 7 8 9 10 11 12 13 +5V IF output Label Figure 2 4706 PH5 Mechanical Drawing, Version 3x8264 3X 8264 ED Revision: 02 September 01 Page 2 of 15 8264ED02.doc 4706 PH5 TUNER MODULE (3X 8264, 3X 8287, 3X 8320) ADVANCE DATA SHEET CABLE MODEM APPLICATIONS PIN CONNECTION 1 Reverse channel in 2 3 65.94 F-CONNECTOR 4 Supply voltage VS1 + 5 V for power supply 5 AGC voltage 6 Switch port P6 output/input for ADC 7 NC 8 Supply voltage VS1 for tuner + 5 V 9 IIC bus signal SCL 10 IIC bus signal SDA 18 2 1 4 3 5 6 7 8 9 11 Address selection for IIC bus 10 11 12 13 12 IF output Label Figure 3 13 IF output 4706 PH5 Mechanical Drawing, Version 3x8287 PIN 1 CONNECTION Reverse channel in 2 65.94 3 4 18 1 2 3 Figure 4 4 5 6 7 8 9 10 11 12 13 Supply voltage VS1 + 5 V for power supply 5 AGC voltage 6 Switch port P6 output/input for ADC 7 NC 8 Supply voltage VS1 for tuner + 5 V 9 IIC bus signal SCL 10 IIC bus signal SDA 11 Address selection for IIC bus 12 IF output 13 IF output 4706 PH5 Mechanical Drawing, Version 3x8320 3X 8264 ED Revision: 02 September 01 Page 3 of 15 8264ED02.doc 4706 PH5 TUNER MODULE (3X 8264, 3X 8287, 3X 8320) ADVANCE DATA SHEET CABLE MODEM APPLICATIONS 4.2 MECHANICAL CHARACTERISTI CS Table 1 Mechanical Characteristics CHARACTERISTIC DIMENSIONS Dimensions According to drawings in Figures 2 through 4 Weight Approximately 41g Plug holding strength Plug according to IEC 169-2 Plug according to SCTE spec.
