M I C R O T U N E™ 4737 PY5 RF TUNER MODULE (3X7180, 3X8568) ADVANCE DATA SHEET CABLE MODEM APPLICATIONS 1 APPLICATIONS The 4737 PY5 RF Tuner Module is designed for subscriber-side cable modem applications. 2 FEATURES • • EuroDOCSIS compatible VHF Low, VHF High, and UHF • • • • All functions controlled by I2C bus Downstream frequency range from 80 MHz to 860 MHz Upstream frequency range from 5 MHz to 65 MHz Antenna input: F-connector 3 INTRODUCTION The 4737 PY5 RF Tuner Module covers a frequency range from 80 MHz to 860 MHz with a channel bandwidth of 6 MHz for downstream signals, and 5 MHz to 65 MHz for upstream signals. Figure 1 4737 PY5 RF Tuner Module The receiver uses a single-conversion approach with the reception frequency range divided into VHF low, VHF high, and UHF. Band selection and tuning is done via the I2C -bus. An automatic gain control (AGC) input allows for external control of the output signal amplitude. 3X 7180 ED Revision: 02 August 00 Page 1 of 14 7180ED02.doc 4737 PY5 TUNER MODULE (3X 7180, 3X 8568) ADVANCE DATA SHEET CABLE MODEM APPLICATIONS The common antenna input/output is realized by an F-connector (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. 4 MECHANICAL SPECIFICATIONS This section contains mechanical specifications for the 4737 PY5 RF Tuner Modules. 4.1 MECHANICAL DRAWING PIN 1 CONNECTIO N Reverse channel 2 3 65,94 F-CONNECTOR 18.0 1 2 3 4 5 6 7 8 9 10 11 12 13 4 Supply voltage VS1 for Power Supply 5 AGC voltage 6 switch port P6 output/input for 7 supply voltage VS2 8 supply voltage VS1 for tuner 9 IIC bus signal 10 IIC bus signal 11 address selection for IIC 12 IF output 13 IF output +5V Label Figure 2 4737 PY5 Mechanical Drawing, Version 3x7180 3X 7180 ED Revision: 02 August 00 Page 2 of 14 7180ED02.doc 4737 PY5 TUNER MODULE (3X 7180, 3X 8568) ADVANCE DATA SHEET CABLE MODEM APPLICATIONS 4.2 MECHANICAL CHARACTERISTI CS Table 1 Mechanical Characteristics CHARACTERISTIC DIMENSIONS Dimensions According to drawing 3x7632 GZ for 3x7180 and 3x8568 GZ Weight Approximately 41g Plug holding strength Plug according to SCTE spec.
