Design a Ku-band VSAT transmitter or transceiver that meets IESS-308
NXP Ku-band RF LO Generator IC’s for VSAT
The TFF100xHN family are Ku-band RF PLLs, with integrated VCO intended for low phase-noise
Local Oscillator (LO) circuits in Ku-band VSAT transmitters and transceivers. Manufactured in a high-
performance SiGe:C process, it delivers extremely low phase noise and complies with the IESS-308
from Intelsat.
Features
` Phase noise compliant with IESS-308 (Intelsat)
` Differential input and output
` Divider settings at 16, 32, 64, 128 or 256
` Lock-detect output
` SiGe:C technology (120-GHz f
` HVQFN24 (SOT616-1) package
Applications
` VSAT block-up-converters
` VSAT down conversion
` Local oscillator signal generation

VSAT networks are commonly used to transmit narrowband
data, such as point-of-sale transactions for credit cards, or to
transmit broadband data that supports satellite Internet access
to a remote location, VoIP, or video.
The network typically consists of a dish antenna, an outdoor
unit, and an indoor unit. The outdoor unit is used for
frequency translation between RF and IF, and usually includes
a microwave-based uplink/downlink separator, a Low Noise
Block (LNB) for receiving the downlink signals, and a Block Up
Converter (BUC).
The VSAT IC’s can be used to create the LO generator for a
linear BUC (meaning the IF or RF conversion is done by mixing
with an LO).
To enable precise frequency and time multiplexing, the
downlink signal provides an accurate frequency reference of 10
MHz. The indoor unit frequency multiplexes this with the uplink
IF signal, and the LO signal in the BUC needs to be frequency
locked to the reference.
The TFF100xHN IC’s are housed in a 24-pin HVQFN (SOT616-1)
package. The pins have been assigned for optimal performance.
Three voltage domains are used to separate the block on the
IC, and two pins for each output (OUT-P) and OUT-N) have been
reserved to match a typical layout using a linewidth of Z = 50 Ω
microstrip on a 20-mil RO4003 board (1.1 mm).
The ground pins have been placed next to the reference input
and the output, and, to minimize crossings in the application,
all the supply pins are on the same side of the IC.
