Renesas UPD5753T7G-E1-A

Overview

UPD5753T7G-E1-A from Renesas Electronics is a SiGe/CMOS integrated IF switch matrix IC with 4 × 2 RF signal routing capability, tone/voltage control interface, and operation across 250 MHz to 2150 MHz. It delivers 7 dB typical insertion loss, 33 dB typical isolation in worst-case mode, and supports dual-output switching via POLA/TONE control logic. It is used in satellite DBS multiswitch boxes for LNB signal path selection.

For engineers reviewing the UPD5753T7G-E1-A datasheet, UPD5753T7G-E1-A pinout, UPD5753T7G-E1-A application, or UPD5753T7G-E1-A equivalent, key selection criteria include its 20-pin QFN (4 × 4 mm, 0.5 mm pitch) package, dual-tone-controlled 4:2 switching architecture, POLA voltage threshold of 14.75 V (typ), and compatibility with +3.3 V supply and 50 Ω RF systems.

Technical Context

The UPD5753T7G-E1-A integrates a 4 × 2 RF switch matrix with a 4:16 decoder-based controller that interprets M0/M1 logic inputs and POLA/TONE analog voltage/pulse signals to route any of four input ports (IN-A to IN-D) to either OUT1 or OUT2. Its enable/disable function is voltage-gated: POLA > 9.5 V activates channel switching.

It operates within −40°C to +85°C ambient, draws 1.9–3.0 mA quiescent current, and maintains ≤1.0 dB insertion loss flatness over 0.95–2.15 GHz. Switching times are 0.75 μs (POLA) and 220 μs (TONE), supporting both fast DC-level and modulated tone-based control schemes in satellite IF distribution.

FAQ

What is the maximum RF input power rating for UPD5753T7G-E1-A?

The UPD5753T7G-E1-A supports a maximum RF input power of +15 dBm per input port (IN-A through IN-D), as specified in the Absolute Maximum Ratings table. Exceeding this level risks permanent damage to internal switch elements and degrades isolation and linearity performance. Operation at +15 dBm is validated only within the recommended operating temperature range (−40°C to +85°C) and with proper 50 Ω impedance matching on all ports.

Does UPD5753T7G-E1-A require external pull-up or pull-down resistors on M0/M1 pins?

No, the UPD5753T7G-E1-A does not require external pull-up or pull-down resistors on M0 and M1 pins. These logic inputs are internally biased and accept direct connection to GND (for logic "0") or VDD (+3.3 V) (for logic "1"), as defined in the Truth Table on page 5 of the datasheet. Adding external resistors may interfere with switching thresholds and is unnecessary for compliant operation.

Can UPD5753T7G-E1-A operate with a 5 V supply instead of 3.3 V?

No, UPD5753T7G-E1-A is not rated for 5 V operation. Its Absolute Maximum Rating for VDD is +4.0 V, and Recommended Operating Range is +3.0 V to +3.6 V. Applying 5 V exceeds absolute maximum limits and will cause irreversible damage. The device must be powered from a regulated +3.3 V supply with appropriate decoupling (1000 pF ceramic capacitor near VDD pin).

What is the thermal pad connection requirement for UPD5753T7G-E1-A?

The exposed thermal pad on the underside of the UPD5753T7G-E1-A QFN package must be soldered directly to a solid GND copper pour on the PCB. This pad serves as both thermal dissipation path and primary RF return. The datasheet specifies it is electrically connected to GND internally, and failure to connect it results in excessive junction temperature (>125°C) and potential parametric shift or failure at rated power levels.

How does the POLA control voltage interact with the TONE signal in UPD5753T7G-E1-A?

In UPD5753T7G-E1-A, POLA and TONE operate independently but concurrently: POLA voltage (≥9.5 V) enables the switch matrix for a given output (OUT1 or OUT2), while TONE frequency (18–26 kHz) selects which input (IN-A to IN-D) connects to that enabled output. Both signals must be present and valid simultaneously for functional routing-e.g., POLA1 high + TONE1 at 22 kHz routes IN-A to OUT1. The Truth Table on page 5 details all valid combinations.
