Texas Instruments TLC5510IPW

Overview

TLC5510IPW from Texas Instruments is a CMOS 8-bit, 20 MSPS analog-to-digital converter (ADC) with semiflash architecture, 2-V full-scale input range, ±0.75 LSB integral linearity error at 25°C, and single 5-V supply operation. It integrates internal reference resistors, parallel high-impedance digital outputs, and sample-and-hold circuitry - optimized for video digitization in digital TV and medical imaging systems.

For engineers reviewing the TLC5510IPW datasheet, TLC5510IPW pinout, TLC5510IPW application, or TLC5510IPW equivalent, key selection criteria include its 2-V input span, TSSOP-24 package compatibility, 2.5-clock latency, differential linearity of ±0.5 LSB at 25°C, and support for NTSC ramp inputs at 20 MSPS without external reference components.

Technical Context

The TLC5510IPW implements a two-step semiflash conversion architecture: upper and lower 4-bit comparator blocks operate in pipelined fashion, reducing comparator count and power versus full-flash ADCs. Its internal resistor divider (320 Ω / 270 Ω / 80 Ω) generates a nominal 2-V reference between REFT and REFB when REFTS and REFBS are shorted to their respective terminals.

Digital output timing features 18–30 ns delay (td(D)), 5 ns enable time (ten), and 7 ns disable time (tdis) under CL ≤ 10 pF load. Aperture jitter is 30 ps, sampling delay is 4 ns, and analog input bandwidth is 14 MHz (–1 dB), enabling accurate digitization of composite video and QAM signals.

FAQ

What is the full-scale input voltage range of the TLC5510IPW?

The TLC5510IPW has a 2-V full-scale analog input range. This is achieved using its internal resistor divider network (320 Ω / 270 Ω / 80 Ω) between VDDA and AGND, with REFT and REFB configured as top and bottom reference nodes. External jumpers (shorting REFT↔REFTS and REFB↔REFBS) activate this mode - no external reference IC or resistors are needed for standard video-level operation.

Does the TLC5510IPW require an external clock driver?

No, the TLC5510IPW accepts standard CMOS-level clock inputs directly. Its CLK pin is compatible with 5-V logic families and specifies minimum high/low pulse widths of 25 ns. For optimal jitter performance, TI recommends driving CLK with a low-noise, low-skew source such as a crystal oscillator or dedicated clock buffer - but no level-shifting or amplification is required for the TLC5510IPW itself.

Can the TLC5510IPW be used with a 4-V input range?

No - the TLC5510IPW is specifically characterized and specified for a 2-V full-scale input range. The 4-V variant is the TLC5510A (e.g., TLC5510AINS). Pinout and package are identical, but internal reference configuration differs: TLC5510IPW uses all three internal resistors to generate 2 V, while TLC5510A uses only the center resistor with external 4-V reference applied. Substituting one for the other without circuit modification will result in incorrect scaling and linearity errors.

What is the purpose of the OE (output enable) pin on the TLC5510IPW?

The OE pin on the TLC5510IPW provides active-low control of the D1–D8 parallel output drivers. When OE is low, data is driven onto the bus; when OE is high, all eight outputs enter high-impedance state. This enables time-multiplexed sharing of the data bus among multiple devices and prevents bus contention during idle periods - essential in FPGA- or microcontroller-based video capture systems with multiple ADC channels.

Is the TLC5510IPW pin-compatible with the Sony CXD1175?

Yes - the TLC5510IPW is explicitly stated in the datasheet as interchangeable with the Sony CXD1175. Both devices share identical pinout, 2-V full-scale range, 20 MSPS operation, and TSSOP-24 packaging. This interchangeability was validated by TI for drop-in replacement in legacy video equipment designs originally specifying the CXD1175, including matching timing parameters and DC specifications.
